oneisall is a pet-care brand best known for grooming tools, and it now sells air purifiers made specifically for homes with dogs and cats. Pet air purifiers aim to catch three things: loose fur that floats around the room, dander (tiny flakes of skin that often trigger allergies) and odors. The key idea for new owners is that a good pet purifier usually has more than one layer. A coarse pre-filter grabs fur first, so the finer HEPA filter behind it does not clog as quickly.
The three products here fit together simply: the PP02 is a compact pet purifier, the 20-pack of washable pre-filters is made for the PP02, and the PP04 is a HEPA purifier sold for large rooms and cat owners.

How Pre-Filters and HEPA Filters Work Together
Before comparing models, it helps to know what happens inside a pet air purifier. A fan pulls room air through a stack of filters. The first layer is usually a pre-filter, a mesh or fibrous sheet with fairly large openings. Its job is to trap the big stuff: clumps of fur, lint and dust bunnies. Pets shed constantly, so this layer fills up faster than anything else in the machine.
Behind it, many purifiers use a HEPA filter. HEPA stands for High Efficiency Particulate Air, a dense pleated paper filter designed to catch very small particles such as dander and pollen. HEPA filters are usually not washable, so protecting them with a pre-filter can help them last longer. Some purifiers also add activated carbon, a porous material that absorbs odor molecules, which matters if you have a litter box nearby.
Keeping the pre-filter clean is the easiest way to keep a purifier working well. When it is packed with fur, airflow drops and the machine cleans less air. That is why a pre-filter refill pack, like the one below, can be as useful as the purifier itself.
oneisall Pet Air Purifiers for Home,PP02 for Compact Spaces
The oneisall Pet Air Purifiers for Home,PP02 is sold as a pet air purifier for home use. Its listing is very short. It gives product dimensions of 5.91 x 7.87 x 5.91 inches and a weight of 9 pounds, and names the model number PP02. Those measurements describe a small footprint, though 9 pounds is heavy for a box that size, so the dimensions may not reflect the full unit.
The listing does not specify the filter layers, whether it uses HEPA or carbon filtration, the room size it covers, fan speeds, noise level or any smart features. What we do know from the separate pre-filter pack is that oneisall sells washable pre-filters made for the PP02 to catch pet fluff, hair and dander. That suggests the PP02 uses a replaceable pre-filter stage in front of its main filter, but check the product manual for the full filter design.
The PP02 suits someone with a small bedroom, home office or pet corner who wants a purifier from a pet-focused brand and plans to keep spare pre-filters on hand. If you need to clean a large living room and want HEPA stated clearly on the box, the PP04 is the better match.

oneisall 20-Pack Washable Pre-Filters
Best for: PP02 owners with shedding pets
Pros
- 20 pre-filters in one pack
- Washable per listing
- Made to catch fluff and dander
Cons
- Only fits the PP02
- Carbon fiber and washable claims unexplained
The oneisall 20-Pack Washable Pre-Filters are made for the oneisall PP02 pet air purifier. The listing says they adsorb pet fluff, hair and dander. “Adsorb” here simply means the fibers hold onto particles on their surface. The pack contains 20 pieces and weighs 9.92 ounces in total.
The material is listed as carbon fiber, and the pack measures 12.99 x 2.48 x 10.98 inches. The listing calls them washable but does not explain how to wash them, how many times each can be reused, or how often to swap one out. Carbon material can lose its odor-absorbing ability when washed, so follow the directions on the packaging. The listing also does not say they fit any purifier other than the PP02.
This pack is for current PP02 owners, or for anyone giving a PP02 as a gift who wants to add a supply of spare filters. With 20 pieces, a heavy-shedding household can change pre-filters often without running out. PP04 owners should not buy this pack, since the listing names only the PP02.

oneisall Pet Cat HEPA Air Purifier
Best for: Cat owners with a large room
Pros
- HEPA named in title
- Labeled for large rooms
- Lighter than PP02 at 8.8 lb
Cons
- Coverage area not given
- Filter details not listed
The oneisall Pet Cat HEPA Air Purifier (model PP04) is the model whose title names HEPA filtration, cats and large rooms. It measures 11.1 x 11.1 x 21.1 inches, a tall tower shape, and weighs 8.8 pounds, slightly less than the listed weight of the PP02.
The listing does not specify the exact room coverage, the HEPA grade, whether a pre-filter or carbon layer is included, the fan speeds, noise level or replacement filter part number. Based on the title alone, it is intended for bigger spaces than the compact PP02, and the HEPA filter should help with fine dander in addition to loose fur.
The PP04 suits cat owners and anyone with a large open living area, especially if someone in the home has pet allergies. Because the replacement filters are not listed here, confirm what refills it uses before you buy. If your space is small, the PP02 takes up less floor room.
How to Choose the Right oneisall Pet Air Purifier
Start with room size. The PP04 is labeled for large rooms, while the PP02 has a smaller listed footprint and no stated coverage. Put the purifier in the room where your pet spends the most time, such as a bedroom or the space near a litter box.
Next, look for HEPA if allergies are a concern. Only the PP04 title names HEPA. If someone sneezes around your cat or dog, that stated filter type is a meaningful reason to pick it. For more general allergy advice, our guide to an air purifier for allergies and pet hair explains filter grades in more detail.
Plan for filter upkeep. Pet hair fills pre-filters quickly. The 20-pack of washable pre-filters makes the PP02 easier to maintain, while PP04 owners should find the correct refill before the first filter wears out.
Think about placement and noise. Neither listing gives a decibel rating, so if the purifier will run in a bedroom overnight, check the manual for a sleep or low-speed setting. If you are weighing larger whole-home options, see our look at a home air purifier for bigger spaces.
Finally, remember that a purifier helps but does not replace grooming. Brushing your pet regularly removes loose fur before it ever reaches the air.
