Airmega 400S

I've got a Coway unit. [Their 400 model](https://www.amazon.com/dp/B0722YZ1R1?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_7&th=1). I've had it for 6 years now and it's still great. Actually I've got a 4 of them. 1 on each floor of my house that runs 24/7 and another in my home bar/cigar lounge that runs when I'm down there having a cigar. I buy an aftermarket filter. Usually [this one](https://www.amazon.com/dp/B083FLKPYS?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_12&th=1). I find it works just as well as the OEM and is much cheaper. $35 instead of $110.

I’ve got two cats and a dog, so air purifiers were kind of a must for me. I’ve tried a few, and the one that made the biggest difference was the Coway Airmega 400S. It’s pricey, but it actually cleared that faint pet smell that never goes away no matter how much you clean.

Wirecutter has been recommending the Coway Airmega for years now. I’ve bought several for myself and family (especially during wildfires) and they’ve performed brilliantly. Filter replacement costs are not terrible. You can use the HEPA filter for like a year and it costs maybe 40 bucks to replace. The charcoal odor filters are very cheap and last a few months. The pre-filter is permanent and you just vacuum that off every few weeks.

One my cats (the reason I originally bought the first one) knocked it over pretty badly and knocked the fan out of alignment. It made a little wobbly noise but just kept running for ages after that anyway.

You can set it quite low, like a “gentle whoosh” of rushing air for overnight use. You can also set it generally to ramp up or down depending on what’s going on with the air (I’ve found that if I’m cooking, for example, it will kind of freak out for bit until it likes the quality of the air. Same if I’m cleaning and kick up a bunch of dust). The newer models will also let you shut off all their LEDs so it’s not glaring in a bedroom when people are sleeping.

I don’t know if it’s available in your country but I just rent mine! I have a Coway and they clean and replace the filters every 3 months (included in the rental cost). I will probably end up upgrading to a bigger one once our contract has ended as we moved to a bigger place. I like it because it has a pet mode.
