Replacement Filters for Aucleia KQ-31 and KQ-36 Purifiers

Aucleia makes compact HEPA air purifiers, and its KQ-31 and KQ-36 models are common in bedrooms, apartments and home offices. Like any HEPA purifier, they only work as well as the filter inside, and a clogged filter means weaker airflow and lingering odors. If you travel often, it is worth keeping a spare on hand so you can swap filters when you return home, after the house has sat closed for weeks, or before the pollen season starts.
Only one of these six filters is made by Aucleia itself, the True H13 HEPA filter for the KQ-31, while the other five are third-party compatibles from Harebery, iSingo and GoKBNY, and the key split is simple: three fit the KQ-36 and KQ-36A, three fit the KQ-31 and KQ-31A, and they are not interchangeable.

- 90-day return window
Cons

Best for: KQ-36 owners wanting one spare filter
Pros
- Fits KQ-36 and KQ-36A
- 3-stage with activated carbon
- Two filters per pack
- Tool-free install steps
Cons
- Third-party, made by Harebery
- No HEPA grade stated
The 2 Pack KQ-36 Filter Replacement Compatible filters are made by Harebery, not Aucleia. The listing states they fit the Aucleia KQ-36 and KQ-36A with no adjustments. Each filter uses a triple-layer design: a dense pre-filter, a “premium filter layer” and activated carbon to capture airborne particles and manage odors from cooking, pets and daily activities.
Notably, the listing does not call the middle layer HEPA or give an efficiency rating, so it is not directly comparable with filters that claim H13 or 99.97% performance. The seller recommends replacing every 3 to 6 months and lays out a tool-free swap: turn off the purifier, open the front panel, replace the filter and reset the system. The listed product weight is 1.79 pounds.
This 2-pack suits a KQ-36 owner who wants a filter in the purifier and one in the closet for the next swap. If you want a stated HEPA rating for a KQ-36, the iSingo 2-pack below makes that claim, and if you want a full year’s supply, the Harebery 3-pack covers more swaps.

Pros
- Fits KQ-31 and KQ-31A
- HEPA, 99.97% at 0.3 microns claim
- 360-degree round design
Cons
- Third-party, sold by iSingo
- Brand shown two ways
The KQ-31 Filter for Aucleia KQ-31 is a third-party 2-pack. The listing brand shows as AddtoYourCart, while the brand name and manufacturer fields say iSingo, so treat it as an iSingo filter sold through that storefront. It fits the Aucleia KQ-31 and KQ-31A and several other KQ-31 purifiers sold under different names.
It uses a round, cylindrical design with 360-degree intake and a 3-stage system of pre-filter, HEPA filter and activated carbon, and the seller claims it captures 99.97% of airborne particles as small as 0.3 microns. The listing says to replace it when all three indicator lights blink together, and recommends every 3 to 6 months. Each filter measures 10.82 x 12 x 6.3 inches by the listing.
This suits KQ-31 owners who want a HEPA claim in a 2-pack. If you prefer the original part, the Aucleia True H13 filter is the genuine option for the KQ-31.

2 Pack KQ-36 KQ-36A Filter Replacement for Pet Households
The 2 Pack KQ-36 KQ-36A Filter Replacement is another iSingo filter sold under the AddtoYourCart storefront. It fits all colors of the Aucleia KQ-36 and KQ-36A, which the listing describes as a purifier covering up to 2,100 square feet, and the seller stresses that it is only for those two models.
The 3-stage system uses a nylon pre-filter, a HEPA layer and activated carbon, with a claim of capturing 99.97% of particles down to 0.3 microns. The seller highlights “2X activated carbon particles” and a HEPA layer with special treatment for pollen and pet odors, aimed at pet dander and hair. The listing also gives a MERV 13 rating and a pleated construction, and offers a 90-day return and exchange window. There is an inconsistency on quantity: the title and unit count say two filters, but the number of items field says one.
Pick this for a KQ-36 in a home with pets where odor control matters. If you do not have pets and want more spares, the Harebery 3-pack may suit you better.

Pros
- Genuine Aucleia filter
- True H13 HEPA
- Fits all KQ-31 and KQ-31A colors
- 5-year warranty listed
Cons
- Single filter only
- Reusable claim is unclear
The Aucleia True H13 HEPA Replacement Filter is the only genuine Aucleia filter in this roundup. It is designed for the KQ-31 and KQ-31A and fits all colors of those models. It uses a 360-degree 3-stage filtration system to capture dust, pet hair and pollen while reducing household odors and smoke.
Aucleia recommends replacing it roughly every 1,800 hours of use, or when all three indicator lights flash together, and installation takes seconds with no tools. The brand notes that using an original filter helps maintain consistent airflow and filtration. It is a single filter weighing 9.92 ounces, and the listing states a 5-year warranty.
Two listing details are unclear. The specifications say “Reusable,” yet the product is a replacement HEPA filter with a stated replacement interval, and HEPA media is generally not designed to be washed. The material field lists ABS plastic, which likely describes the frame rather than the filter media. Follow the replacement guidance rather than trying to clean it. The listing also includes gift-packaging copy that describes the purifier rather than the filter. This suits KQ-31 owners who want the original part and are fine buying one at a time.

3 Pack KQ-36 Filter Replacement Compatible for a Year of Spares
Best for: KQ-36 owners stocking up for the year
Pros
- Three filters per pack
- Fits KQ-36 and KQ-36A
- Activated carbon odor layer
Cons
- Third-party, made by Harebery
- No HEPA grade stated
The 3 Pack KQ-36 Filter Replacement Compatible set is the Harebery KQ-36 filter in a larger pack. The features match the 2-pack: a fit for KQ-36 and KQ-36A with no adjustments, a triple-layer pre-filter, filter layer and activated carbon design, a 3 to 6 month replacement recommendation, and the same tool-free swap steps. It weighs 2.48 pounds.
As with the 2-pack, the listing does not name the middle layer as HEPA or give an efficiency figure.
At a 3 to 6 month interval, three filters can cover roughly a year or more of use, which suits a KQ-36 owner who does not want to reorder before every trip. If you only want one spare, the Harebery 2-pack is enough.

2-Pack KQ-31 Replacement Filter Compatible for Budget Replacements
Best for: KQ-31 owners on a replacement budget
Pros
- Fits KQ-31 and KQ-31A
- H13 layer plus activated carbon
- Disposable, no tools needed
Cons
- Third-party, made by GoKBNY
- Shorter 3-4 month interval
The 2-Pack KQ-31 Replacement Filter Compatible set is made by GoKBNY. It fits the Aucleia KQ-31 and KQ-31A and several other KQ-31 purifiers sold under other names, and the seller asks you to check your model before ordering.
The 3-layer system combines a pre-filter, an H13 true HEPA layer (written as “H13 true HP” in the listing) and activated carbon. It is disposable, slides in with no tools, and the seller recommends replacement every 3 to 4 months, a shorter interval than the other listings. Materials are fiberglass, activated carbon and polyester, and the listing also gives a MERV 13 rating. MERV and HEPA grades are different rating systems, so the two figures describe the filter in different terms rather than confirming each other.
This suits KQ-31 owners who want a two-filter supply and are comfortable with a third-party part. If you would rather stick with the original, the Aucleia True H13 filter is the genuine alternative.
Before you choose
How to Choose the Right Aucleia Replacement Filter
Start with your model number. The KQ-31 and KQ-31A use a different filter from the KQ-36 and KQ-36A. Check the label on your purifier before ordering. The Harebery 2-pack, iSingo KQ-36 2-pack and Harebery 3-pack fit the KQ-36 family, while the iSingo KQ-31 2-pack, the Aucleia True H13 filter and the GoKBNY 2-pack fit the KQ-31 family.
Next, decide between genuine and compatible. Only the Aucleia True H13 HEPA filter is made by Aucleia, and it is for the KQ-31. For the KQ-36, every option here is third-party. Third-party filters can fit well but their performance claims come from the seller, not Aucleia.
Look at the filtration claims. The Aucleia filter states True H13 HEPA. The iSingo filters claim HEPA with 99.97% capture at 0.3 microns, and the GoKBNY filter claims an H13 layer. The Harebery filters list a pre-filter, filter layer and carbon without a HEPA rating. For more on how these ratings compare across brands, see our guide to air purifier replacement filters.
Finally, match pack size to your schedule. Most listings suggest replacing every 3 to 6 months, GoKBNY says 3 to 4, and Aucleia says about 1,800 hours. A 2-pack keeps one spare ready for when you come home from a trip; a 3-pack covers a longer stretch. Our roundup of air purifier 2-pack options covers similar spare strategies.
Questions people ask
FAQ
Which filters are genuine Aucleia?
Only the Aucleia True H13 HEPA Replacement Filter for the KQ-31 and KQ-31A. The other five are compatible filters from Harebery, iSingo and GoKBNY.
Can I use a KQ-31 filter in a KQ-36?
No. Each listing names either the KQ-31 family or the KQ-36 family. The iSingo KQ-36 listing specifically says it fits only the KQ-36 and KQ-36A.
How often should I replace an Aucleia filter?
Aucleia recommends about every 1,800 hours or when all three indicator lights flash. The third-party listings suggest every 3 to 6 months, or 3 to 4 months for the GoKBNY filter.
Is there a genuine Aucleia filter for the KQ-36 here?
Not in this roundup. All three KQ-36 options are third-party compatibles.
Can I wash the Aucleia H13 filter?
The listing marks it reusable, but it also gives a replacement interval and describes it as a replacement HEPA filter. HEPA media is generally not washable, so plan to replace it.
Should I keep a spare filter when traveling?
A spare lets you swap in a fresh filter as soon as you return, which is helpful if the home sat closed or pollen season arrived while you were away. A 2-pack gives you that spare without overbuying.
