More Details on Our Top Picks
FiTSTILL Reusable Anti-Fog Inserts for Action Camera Housings, 24 Count
The FiTSTILL inserts suit camera owners who would rather dry and reuse moisture absorbers than replace them after a short run. Their silica gel and cellulose fiber construction targets humidity inside a sealed housing, where condensation can cloud footage, and the pieces can be cut to fit different interiors. Compared with the YALLSAME foam inserts, FiTSTILL specifies reuse by baking at 300°F for five minutes rather than approximately five uses, making its reset method clearer for repeat use. The tradeoff is that every reset takes oven time, and the small 25 × 12 mm pieces may need trimming or careful positioning. Its broad listed compatibility also makes it a flexible pick, though the buyer still needs to check that an insert fits without interfering with the camera or housing seal.
Pros:- Reusable after baking at 300°F for five minutes
- Can be cut to fit different housing interiors
- Listed compatibility covers several action-camera brands and models
- Silica gel and cellulose fiber are intended to absorb moisture inside the housing
Cons:- Reuse requires oven heating and cooling
- Small pieces may need trimming or careful placement
- A snug fit must be checked for each housing
Best for: Action-camera owners who regularly use waterproof housings and are comfortable oven-drying inserts between sessions
Not ideal for: Travelers or divers who need a ready-to-use insert without access to an oven, or buyers who do not want to trim and position small pieces
- Quantity:24 inserts
- Dimensions:25 × 12 mm each
- Material:Silica gel on cellulose fiber
- Reuse method:Bake at 300°F for 5 minutes; cool before handling
- Compatible cameras:GoPro Hero, Xiaomi Yi, SJ4000/SJ5000, DJI Osmo Action, Osmo 360, Pocket 3, Insta360 X2–X5
- Item weight:0.1 kg
- Warranty:24 months
Our verdict“Choose FiTSTILL if you want reusable, cut-to-fit inserts and can accommodate oven drying between camera sessions.”
Elecphbo Reusable Anti-Fog Inserts for Action Camera Housings, 60 Count
With 60 reusable inserts, Elecphbo is a practical choice for people who keep several housings ready or shoot often enough to want a larger supply on hand. Like the FiTSTILL 24-count pack, it uses silica gel and cellulose fiber and calls for a 300°F, five-minute oven drying cycle. The bigger count reduces the pressure to ration pieces, but the product data gives less detail about individual dimensions and named camera models than FiTSTILL does; buyers should confirm fit inside their particular housing. Its listed compatibility spans GoPro, SJCAM, Yi, DJI Osmo, and Insta360, while placement still varies by camera. The claimed waterproof rating does not remove the need to keep inserts positioned inside a compatible housing rather than treating them as protection for the camera itself.
Pros:- Pack includes 60 inserts
- Reusable after oven drying at 300°F for five minutes
- Silica gel and cellulose fiber are designed to absorb housing moisture
- Compatibility lists several major action-camera brands
Cons:- Oven drying is required to reuse the inserts
- Placement depends on the housing and camera model
- The provided product data does not specify insert dimensions
Best for: Frequent action-camera users, clubs, or households maintaining multiple compatible waterproof housings
Not ideal for: Occasional users who need only a few inserts, or camera owners who require specified piece dimensions before buying
- Brand:Elecphbo
- Quantity:60 inserts
- Material:Silica gel and cellulose fiber
- Compatibility:GoPro, SJCAM, Yi, DJI Osmo, Insta360, and other compatible action-camera housings
- Reuse instructions:Bake at 300°F for 5 minutes to remove absorbed moisture
- Water resistance level:Waterproof
- Item weight:0.03 kg
- Warranty:180 days
Our verdict“Pick Elecphbo when a large reusable supply matters more than having detailed dimensions or model-by-model fit information.”
48-Pack Anti-Fog Inserts for Action Camera Waterproof Housing
This 48-piece pack is aimed at buyers who want a straightforward supply of inserts for waterproof housings without managing an oven-drying routine. The product description emphasizes easy insertion and broad compatibility, including GoPro and other action cameras, but it does not identify the insert material, dimensions, or a reuse method. That makes it less specified than FiTSTILL, which provides both dimensions and baking instructions, and less clearly reusable than YALLSAME. The pack size may suit a series of underwater sessions, yet the stated possibility of frequent replacement makes its long-term use less predictable than the reusable options. It is intended for housing interiors, not direct application to a camera lens, so buyers should not expect it to address condensation on exposed optics.
Pros:- Includes 48 pieces for stocking multiple sessions or housings
- Designed for use inside waterproof camera housings
- Described as easy to insert without tools
- Compatibility is presented as universal for most action cameras
Cons:- Product data does not specify material or individual dimensions
- May need frequent replacement during extended use
- Not intended for treating fog on camera lenses
Best for: Underwater action-camera users who want a larger pack of simple inserts and do not need a stated oven-reuse process
Not ideal for: Buyers seeking documented materials, exact insert dimensions, or a defined reusable product for repeated trips
- Quantity:48 pieces
- Compatibility:Universal fit claim for GoPro and other action cameras
- Purpose:Anti-fog inserts for waterproof housings
- Use:Insert into housing to help reduce condensation
- Insertion:Described as easy to insert without tools
- Reuse information:No reuse method specified
Our verdict“Choose this pack for straightforward housing inserts when its limited material and reuse details are acceptable.”
YALLSAME Reusable Anti-Fog Inserts for Action Camera Waterproof Housings, 30 Pieces
YALLSAME’s strongest distinction is its five vacuum packs, which let buyers keep portions separate until needed rather than opening one large supply at once. Each 25 × 12 mm foam insert can be cut to fit and is listed for approximately five uses, with a shorter two-minute oven-drying cycle than the five-minute instructions for FiTSTILL and Elecphbo. That can make resets more convenient, but the stated reuse limit is less compelling for buyers who want a long-running supply. Its 30 pieces and compatibility with GoPro, DJI Osmo Action, Insta360, AKASO, and SJCAM make it a useful middle ground, though it offers fewer inserts than Elecphbo’s 60-count pack. The foam format and pack separation suit organized trip preparation, not buyers who want the highest count or a clearly specified silica-gel blend.
Pros:- 30 inserts are divided among five vacuum packs
- 25 × 12 mm pieces can be cut to fit
- Reusable for approximately five uses, according to the product data
- Compatible with several action-camera housing brands
Cons:- Each insert is listed for approximately five uses
- Reuse requires oven drying at 300°F
- The 30-piece count is smaller than Elecphbo’s 60-count pack
Best for: Traveling action-camera owners who want individually portioned stock and a defined, short oven-drying routine
Not ideal for: High-volume users who want the largest pack or buyers seeking inserts with a stated silica gel and cellulose fiber construction
- Model number:20801
- Quantity:30 inserts
- Packaging:5 vacuum packs
- Material:Foam
- Dimensions per insert:25 × 12 mm
- Reuse:Approximately 5 uses; dry in an oven at 300°F for 2 minutes
- Compatibility:Waterproof housings for GoPro, DJI Osmo Action, Insta360, AKASO, and SJCAM
- Warranty:1 year
Our verdict“Pick YALLSAME if separated packs and a stated short reset cycle matter more than maximum reuse or pack size.”
Wisesorb 100-Pack Desiccant Inserts for Camera Housings
Wisesorb earns the bulk-supply role with 100 desiccant inserts, the largest stated count in this group. That quantity is useful for users who prepare many housings or want a reserve for frequent underwater sessions, but the product data lists compatibility specifically with GoPro, SJCAM, and Yi, a narrower range than FiTSTILL or Elecphbo. Its silica gel and cellulose fiber construction is intended to absorb housing moisture, and the inserts can be cut for a closer fit. Unlike FiTSTILL, however, Wisesorb does not provide dimensions or a reuse and drying method, so buyers have less guidance for sizing and ongoing use. The bulk count is its clear advantage; it makes less sense for someone with one camera who values detailed fit instructions over quantity.
Pros:- Largest stated pack count in this group, at 100 inserts
- Silica gel and cellulose fiber are intended to absorb moisture
- Can be cut to fit different housing shapes
- Listed compatibility includes GoPro, SJCAM, and Yi housings
Cons:- Compatibility is listed for fewer camera brands than FiTSTILL or Elecphbo
- No insert dimensions are provided
- No reuse or drying method is specified
Best for: GoPro, SJCAM, and Yi owners who maintain multiple housings or want a large reserve of cut-to-fit desiccant inserts
Not ideal for: Owners of other camera brands or buyers who need specified insert dimensions and documented reuse instructions
- Quantity:100 inserts
- Material:Silica gel and cellulose fiber
- Compatibility:GoPro, SJCAM, and Yi camera housings
- Package dimensions:4.76 × 3.23 × 1.73 inches
- Item weight:1.76 ounces
- Fit adjustment:Can be cut to fit
Our verdict“Choose Wisesorb for a large supply if your housing is listed as compatible and you can work without stated sizing or reuse guidance.”
MEETOOT Reusable Anti-Fog Inserts for Underwater Camera Housings, 48 Pack
MEETOOT’s 48 inserts suit camera owners who want a reusable supply for recurring underwater or humid-weather shoots. The sponge inserts absorb moisture inside a housing, helping reduce the temperature-related fog that can spoil footage. Each can be reused about five times, then dried in an oven at 300°F for 2 minutes; that shorter stated drying cycle sets it apart from the CamKix and HoneTeek inserts, which call for five minutes. The larger HoneTeek pack includes 60 inserts, so it offers more pieces, while MEETOOT’s drying instructions may appeal to buyers who want a shorter reactivation step. The tradeoff is upkeep: inserts need oven drying after use, and the pack does not include a camera. Check your housing’s available space and placement guidance before loading it.
Pros:- Absorbs moisture to help reduce fog inside waterproof housings.
- Each insert is reusable about five times.
- Stated reactivation time is 2 minutes at 300°F.
- 48 inserts provide a substantial supply for repeated shoots.
Cons:- Requires oven drying after about five uses.
- Compatibility depends on the space and fit of the specific housing.
- Camera is not included.
Best for: Action-camera owners who shoot underwater or in humid conditions regularly and want a reusable pack with a short stated oven-drying cycle.
Not ideal for: Buyers seeking inserts that work without periodic oven drying, or anyone expecting a camera to be included.
- Brand:MEETOOT
- Quantity:48 inserts
- Material:Sponge
- Water resistance:Waterproof
- Compatibility:Underwater camera housings, including DJI Osmo Action and other listed action-camera housings
- Reuse:About 5 uses per insert
- Drying instructions:Bake at 300°F for 2 minutes
- Included:48 anti-fog inserts; camera not included
Our verdict“Choose MEETOOT if you want reusable housing inserts and prefer its stated 2-minute drying cycle over the longer reactivation instructions for CamKix or HoneTeek.”
CamKix Reusable Anti-Fog Inserts for GoPro and Other Cameras, 20 Pack
CamKix’s 20-piece pack is the most targeted choice here for owners of older GoPro models: its listed compatibility specifically names the Hero 1, 2, 3, 3+, and 4. The 1.7 × 0.15-inch inserts give buyers a useful size reference for checking whether they fit a particular housing, though placement should still follow the camera maker’s instructions. Like HoneTeek, CamKix uses silica gel on cellulose fiber and requires a five-minute oven bake at 300°F to reactivate. HoneTeek supplies 60 pieces and names more current action-camera brands, so it is a stronger match for buyers who need broad brand coverage or a larger supply. CamKix’s narrower pack is easier to justify when the listed older GoPro compatibility is the deciding factor; the recurring oven step and limited quantity are its main compromises.
Pros:- Specifically lists compatibility with GoPro Hero 1, 2, 3, 3+, and 4.
- Dimensions are provided to help check fit in a housing.
- Silica gel and cellulose fiber absorb moisture that can contribute to fog.
- Can be reactivated by baking at 300°F for 5 minutes.
Cons:- The 20-piece quantity is smaller than the 48-piece MEETOOT and 60-piece HoneTeek packs.
- Requires oven reactivation after absorbing moisture.
- Product data says the inserts are not water resistant.
Best for: Owners of GoPro Hero 1 through Hero 4 housings who want reusable inserts with stated dimensions for fit checking.
Not ideal for: Buyers with newer or less common action cameras who need clearly listed compatibility across a wider range of brands, or those seeking a large pack.
- Brand:CamKix
- Model:ADIRO-20PC-FOG
- Quantity:20 inserts
- Material:Silica gel on cellulose fiber
- Dimensions:1.7 × 0.15 in
- Compatible devices:GoPro Hero 1, 2, 3, 3+; Hero 4 Black and Silver; other camera and housing systems
- Reuse instructions:Bake at 300°F for 5 minutes to remove absorbed moisture
- Water resistance:Not water resistant
Our verdict“Pick CamKix when its explicitly listed older GoPro compatibility and insert dimensions matter more than pack size or broader brand coverage.”
HoneTeek Reusable Anti-Fog Inserts for Action Camera Housings, 60 Count
HoneTeek’s 60-count pack is the strongest fit for households or crews using several action-camera brands. Its listed compatibility spans GoPro, SJCAM, Yi, Insta360, and DJI Osmo Action, a broader named lineup than CamKix’s older-GoPro focus. The silica-gel-and-cellulose-fiber inserts are intended to absorb moisture inside waterproof housings and help prevent lens fog in cold or humid conditions. MEETOOT also lists DJI Osmo Action compatibility and offers 48 pieces, but its sponge inserts have a different material and shorter stated drying time; HoneTeek calls for five minutes at 300°F. That reactivation step and model-dependent placement make this less convenient for buyers who want a fit-and-forget option. Its main advantage is having a large supply with multiple camera brands explicitly named.
Pros:- 60 inserts provide the largest quantity among these three products.
- Lists compatibility with GoPro, SJCAM, Yi, Insta360, and DJI Osmo Action.
- Silica gel and cellulose fiber absorb moisture inside housings.
- Reusable after baking at 300°F for 5 minutes.
Cons:- Requires oven drying before reuse.
- Placement varies by camera model.
- Product data gives no insert dimensions for checking fit.
Best for: Action-camera owners or small crews using multiple brands who want a large pack with broad, explicitly listed compatibility.
Not ideal for: Buyers who need brand-specific placement guidance, want to avoid oven reactivation, or prioritize the shorter drying cycle stated for MEETOOT.
- Brand:HoneTeek
- Quantity:60 inserts
- Material:Silica gel and cellulose fiber
- Reuse instructions:Bake at 300°F for 5 minutes to remove absorbed moisture
- Compatible devices:GoPro, SJCAM, Yi, Insta360, and DJI Osmo Action
- Item weight:0.03 kg
- Use:Absorbs moisture to help prevent fogging on lenses and inside waterproof housings
Our verdict“Choose HoneTeek if you need a generous supply for several named action-camera brands and can accommodate model-specific placement and oven reactivation.”
How We Picked
I evaluated these products based on three primary criteria: absorption efficiency, physical compatibility, and material safety. Absorption efficiency determines how long the insert remains active during a dive, which is critical for preventing condensation on the lens. Physical compatibility was assessed by examining the dimensions and flexibility of each insert to ensure they fit standard action camera housings without obstructing the shutter or lens port. Material safety involved checking for any risk of chemical leakage or residue that could damage sensitive optical coatings.
I also prioritized reusability and ease of maintenance. Products that require simple heat regeneration (like microwaving or oven-drying) scored higher than those requiring complex chemical treatments or single-use disposal. The ranking reflects a hierarchy where reliability and safety in wet environments outweigh pure cost savings, ensuring that the recommended options minimize the risk of water damage to expensive camera equipment.

Factors to Consider When Choosing Antifog Camera Housings
Choosing the right antifog solution requires understanding how moisture behaves in sealed environments. It is not just about absorbing water; it is about managing the thermal differential between the cold water outside and the warm air inside the housing.
Absorption Capacity vs. Physical Size
You might assume that a larger, thicker insert absorbs more moisture, but this is a common mistake. Action camera housings are engineered with tight tolerances. If an insert is too thick, it can prevent the housing backdoor from latching completely, compromising the waterproof seal. I advise prioritizing inserts that are slim yet dense. The best products use high-grade silica gel that packs a high absorption rate into a thin, flexible profile. Always measure your housing’s internal clearance before buying bulk packs to avoid this fitment issue.
Reusability and Maintenance Effort
Most modern inserts are reusable, but the effort required to regenerate them varies. Some silica gel beads change color to indicate saturation, while others remain neutral, requiring you to guess when they are full. I recommend choosing inserts with color-changing indicators if you are not meticulous about tracking usage hours. For frequent divers, the time saved by not having to guess when to dry out the inserts is worth the slightly higher upfront cost. Single-use options are rarely worth it for anyone diving more than once a month.
Adhesive Residue and Lens Safety
Many inserts come with adhesive strips to keep them in place. However, cheap adhesives can leave a sticky residue on the inside of your housing door, which attracts dust and is difficult to clean without risking scratches. I strongly suggest opting for static-cling or silicone-based holders that do not require glue. If you must use adhesive, ensure it is labeled as ‘lens-safe’ or ‘low-residue.’ A ruined lens coating costs far more than a premium set of inserts.
Humidity Environment Adaptation
Not all desiccants perform equally in all climates. Standard silica gel works well in moderate conditions, but if you are shooting in tropical, high-humidity environments, you need inserts with higher saturation capacity. Some premium inserts are impregnated with additional desiccating agents to handle extreme moisture loads. Check the product specifications for relative humidity tolerance. Using a standard insert in a humid jungle river will likely result in fogging, whereas a heavy-duty desiccant pack will maintain clarity.
Cost Per Dive Calculation
When comparing prices, ignore the sticker price and look at the cost per regeneration cycle. A cheap 10-pack might seem attractive, but if each insert only lasts one or two dives before losing effectiveness, it becomes expensive quickly. Bulk packs of 50 or 100 usually offer better value because they allow you to rotate inserts, ensuring you always have a dry one ready. This rotation strategy also extends the life of the silica gel by preventing it from becoming fully saturated for extended periods.
Frequently Asked Questions
Can I use regular silica gel packets from shoe boxes or electronics?
While technically possible, I do not recommend using generic silica gel packets for camera housings. These packets are often made with materials that can shed dust or contain cobalt chloride, which is toxic and can leave residues. They are also typically too thick for the tight interior of an action camera housing, risking a seal failure. Purpose-built antifog inserts are designed with safe, non-dusting materials and slim profiles that fit correctly inside the housing without interfering with the latch mechanism.
How do I know when my antifog insert is no longer working?
Most high-quality inserts feature color-changing indicators, turning from blue or orange to pink or clear when saturated. If your inserts do not have indicators, you can gauge their effectiveness by the presence of fog on the lens during a dive. A reliable method is to weigh the inserts; if they have gained noticeable weight compared to their dry state, they are saturated. For non-indicating packs, I suggest keeping a log of how many dives each insert has survived to establish a replacement schedule.
Does the temperature of the water affect how quickly the housing fogs?
Yes, temperature differentials are the primary cause of fogging. If you enter cold water with a warm camera, condensation forms on the cold glass. Antifog inserts help, but they cannot fully compensate for extreme temperature shocks. To maximize their effectiveness, let your camera and housing acclimate to the ambient water temperature for at least ten minutes before sealing the housing. This reduces the thermal gap, allowing the desiccant to manage the residual humidity rather than fighting a massive condensation event.
How do I clean the inside of my camera housing before inserting a new pack?
Use a microfiber cloth slightly dampened with isopropyl alcohol to wipe down the interior surfaces, including the lens port and the latch gaskets. Avoid using paper towels or rough cloths that can leave lint or scratches. Ensure the housing is completely dry before sealing it with a new insert. Any residual moisture or debris can reduce the effectiveness of the desiccant and potentially damage the camera’s electronics or lens coating.
Are there any risks to leaving an antifog insert inside the housing during storage?
Leaving a saturated insert inside a sealed housing during long-term storage can actually increase humidity levels if the insert releases moisture due to temperature changes. I recommend removing the insert when storing your camera for extended periods, especially in non-climate-controlled environments. Store the inserts separately in a dry, airtight container. This prevents the housing from becoming a humid microclimate that could promote mold growth on gaskets or corrosion on metal parts.
Conclusion
Choosing the right antifog solution depends on your diving frequency and environmental conditions. For most users, the FiTSTILL Reusable Anti-Fog Inserts offer the best blend of size and performance, making them the Best Overall pick. If you dive frequently and need to stock up, the Elecphbo Reusable Anti-Fog Inserts provide the Best Value through their high-count packaging. For professionals working in extreme humidity, the Wisesorb 100-Pack Desiccant Inserts are the Best Premium choice due to their superior absorption capacity. Beginners should start with the CamKix 20 Pack to test compatibility without committing to a large quantity. Always prioritize proper housing acclimation and regular maintenance to get the most out of these inserts.
