Bests & Worsts Reviews from Amazon

There’s a reason this is so highly rated! It does WONDERS for pet allergies when paired with the yellow filter (which is sold separately). Here’s my detailed review. If any of this sounds like your situation, don’t hesitate to get this!! My partner is allergic to all dogs - their dander, fur, and saliva all set him off - and he has seasonal/household allergies along with bad asthma. But, we love dogs and recently rescued a cattle dog mix. We have carpet in our bedroom and her fur gets everywhere. For the first week with our dog and without this air purifier, my partner was extremely itchy and woke up several times a night nearing asthma attacks due to allergies. He’d go sleep in the open living room (with hard floors) to breathe better. Then we bought the Levoit Core 300, paired with the yellow pet allergy filter. He has had zero issues with his allergies at night since it arrived. Our pup will still lick him and her fur still gets everywhere, but along with vacuuming regularly and trying to keep our bed covered with a sheet during the day so dog fur isn’t all in the bed, this purifier has made it possible for him to sleep well and not experience any allergy-induced asthma attacks. It’s truly amazing. We’ve only had it for a couple of nights but I feel confident in writing a review this early because the results are already so obvious. In addition to my partner’s allergies, our apartment seems very dusty within a matter of days after dusting/vacuuming (I’m fairly sure our HVAC system is filthy despite having the ducts “cleaned” by a company our complex hired earlier this year) and the air that comes out of our vents has a somewhat unclean odor. We also live in south Florida, so opening windows to get fresh air isn’t possible except on the rare days when humidity is minimal. The air in our bedroom truly feels cleaner and it doesn’t smell weird like it used to as soon as the AC starts blowing from the vents. I’m also convinced the purifier has helped reduce the odor from my partner’s stinky work socks/shoes (they’re sinful lol). This purifier has made life so much better for us! We are going to buy the 400S for the larger open living/dining/office area of our apartment. Our place is around 770 square feet with the bedroom and kitchen both completely isolated, so having the core 300 for the bedroom and a 400S for the rest of the place should work well for us. If you suffer from pet allergies this will probably do wonders for you like it has for us!!! REMINDER: the pet allergy filter is sold separately. Oh, and I don’t find this to be loud at all. If anything it’s soothing while we sleep. Our 1.5 year old Lasko tower fan and central HVAC system are both louder than this. I also LOVE that you can shut the display lights off at night. We haven’t tried sleep mode or the timer because we just keep it on level 3 all night. I shut it off during the day unless we’re in the room, at which point we put it on a lower setting. We haven’t tried the regular filter that came with the purifier, only because we know we specifically need something for pet allergies. My one and only complaint has nothing to do with the product’s functionality or anything like that: it’s simply that it would be nice if buyers could choose their filter type when purchasing the purifier instead of having the regular one come with it by default - I feel wasteful after receiving the regular one that we probably will never use. But, if a replacement pet filter is not available right away it will be handy to use the regular one temporarily.
