Does the Oneisall Air Purifier actually work on pet hair? I tried it with my shedding dog

If you're after one of the best air purifiers to deal with pet hair and concerned about noise pollution, you're in luck. The Oneisall Air Purifier does both. In fact, I forgot all about it while it was running all day long in my living room, as it’s super quiet and rather compact for the amount of air purification it boasts.

And for the luddite in me, the lack of an app to control the unit actually became a benefit: I didn’t have to think about it at all to get the benefits out of it. But for those who like to control their devices from their phone to turn them on or off, adjust them, or otherwise get tons of data in one convenient place, the lack of an app might be a dealbreaker.

Note that it’s advertised as a pet hair specialist. And while it did suck up some of my dog’s hair (who was shedding like mad during testing), it wasn’t as much of a pet-hair-pro as I was expecting.

Still, the Oneisall Air Purifier is so easy to use and so quiet that it adds peace of mind simply by not being top of mind. Here's what happened when I put it to the test in my home.

Oneisall’s Air Purifier review: Price and availability

The Oneisall Air Purifier is available on Amazon for $80 and on Oneisall’s website for the same price.

In addition, the company offers free shipping, a 30-day money back guarantee, and a stout 24-month warranty.

Oneisall’s Air Purifier review: Design

Despite its relatively small size, the Oneisall Air Purifier packs a lot of punch, according to the spec sheet. The 360-degree dual intake captures 80% more pet hair than a single intake, according to Oneisall. There’s a filter on the front of the unit and another out back to capture junk from both sides.

The H13 HEPA and dual carbon filters remove odors and tiny particles. Oneisall says the unit will capture 99.97% of micro particles and 99.99% of air pollutants, in spaces up to 1,410 square feet, giving it an impressive CADR of 320m3/h (188CFM).

The pre-filters are washable too, so you should get plenty of life out of them. Plus the odor removal comes courtesy of activated carbon, which Oneisall says will freshen your air twice as fast as its competition.

Noise-wise, the air purifier is very quiet on its lowest setting. Oneisall says it operates at just 25 decibels. The noise level will increase, of course, as the fan level goes up. Speaking of which, the unit auto-adjusts fan speed based on information received through its smart sensors.

The LCD screen is positioned at the front top of the unit. It’s color-coded to give you a sense of your current air quality at a quick glance. Green is good; red is bad. You can manually adjust the air flow with the touch screen, but the unit will also auto-adjust based on air quality. You can also lock the screen to prevent accidental adjustments.

In the box, you’ll find the main unit, 2 HEPA filters, power cable, and a cleaning brush. This can be used to dislodge pet hair that accumulates on the filters.

Notably, there is no app to use in conjunction with the Oneisall Air Purifier. So any adjustments to the unit would have to be made at the control panel on the unit itself.

Oneisall’s Air Purifier review: Performance

I plugged in the Oneisall Air Purifier and walked away. That’s it. Super simple, no setup to speak of and no app to download. Honestly, it was refreshing as it seems every device these days requires your email registration in a companion app that may or may not actually be useful. I didn’t miss that part of the setup process, and definitely didn’t miss fiddling with an app.

But if you’re data-obsessed, you’re not going to get much from this unit. The color-coded screen will let you know whether your air quality is good or bad, but you won’t get any other data if you’re the sort who likes to track that sort of thing. I did miss having that information at my fingertips at first, but the longer the unit ran, the more I wondered whether having that granular data really benefitted me in any way. It’s a decision you’ll have to make for yourself. If you’re after a set-it-and-forget-it unit, look no further. Data nerds, look elsewhere.

.One thing I noticed as I played with the various fan settings was the slight difficulty of using the touchscreen buttons. I would press the lighted area that indicates the fan setting, but the setting would not change. It sometimes took two or three presses to get the screen to respond. This didn’t happen all the time, but enough times to be annoying. I had the most success tapping the upper right corner on the top part of the touch screen to get the display to show, and to make the buttons easier to activate. Still, It would be helpful if the touchscreen was more sensitive to touch.

Like many pets, my dog has his favorite spot to spend much of his day. It’s a chair in the corner of our living room that’s almost always covered completely in dog fur and comes with a warning to guests not to sit there for fear of dog sighs and fur coverage. So I positioned the unit next to my pup’s chair and let it run for two weeks.

I was expecting the filters to get pretty furry after constant use for two weeks. But that wasn’t really the case. While there was evidence of a fair bit of dust, there wasn’t much fur at all on the filters or pre-filter. That was surprising, given how much fur coated doggo’s chair. He comes and goes a lot, walking right past the unit, and he often shakes himself as dogs do. So the lack of fur on the filter was a bit of a head scratcher given Oneisall’s claims.

That said, the pre-filters and the filters themselves did seem to catch quite a lot of dust. And a lot of what air purifiers like these are designed to suck up aren’t necessarily visible to the naked eye.

To check in with hard numbers, I used an Alexa air quality monitor. The Oneisall PM2.5 reading on the front of the unit showed 005, which I assume means .005 pmµ/g3. Alexa registered a slightly lower reading than that, at 0035. Again, this seems to be within a reasonable margin of error.

Oneisall’s Air Purifier review: Noise

It’s also super quiet. I forgot it was running most of the time and even found myself checking early on to make sure it was actually on. Granted, the air quality light read green most of the time.

My decibel reading read slightly higher than the advertised level; I got 30 decibels. I’d say this is within a reasonable margin of the advertised level. But even when the air flow fan kicked up a notch, the noise level was a quiet 42 decibels.

On the highest setting, my decibel meter picked up 58 decibels. That’s still much quieter than other units I’ve tested, which creep into the mid-60-s and low 70s at high settings

Oneisall’s Air Purifier review: Accessories

The only accessory that comes with the Oneisall Air Purifier is the cleaning brush. It’s used to dislodge bigger detritus and pet fur from the pre-filters and filters. It’s easy to use and also fairly easy to lose. I wish it had a little mount on the unit itself so I had a place to stow it when not in use.

Otherwise, there aren’t many other accessories to speak of, except for replacement parts. You can buy refill filters on the Oneisall website.

Oneisall’s Air Purifier review: Competition

The air purifier market is very, very crowded. There are tons of options, each one promising varying levels of specialization. Many of Oneisall’s most direct competitors are larger, more expensive, and definitely louder. But some are also more versatile and offer data that the Oneisall can’t.

For instance, the Mila Air Purifier, which you can customize with several different filters, each intended for a different use. It comes with a companion app too, so you get more control and information. But it’s also bigger, louder, and more expensive than the Oneisall, so you'll have to consider what's important for your needs.

Oneisall’s Air Purifier review: Verdict

The Oneisall has a lot going for it: quiet operation and super simple with its app-free use. I was disappointed to see that the filters weren’t more clogged with dog fur after my testing, but that’s not exactly an indication that the Oneisall Air Purifier isn’t doing its job.

If you love data however, you’ll miss the app. Similarly, if you prefer to operate the unit from afar or integrate it into your smart home ecosystem, the Oneisall probably isn’t for you. However, if you just want to 'set-it-and-forget it', the Oneisall Air Purifier is ideal for anyone looking for a simple unit to purify your air without having to think about it.
