Blueair - Blue 3210

Having lived in fires and smog. Theres two easy brands to pick: Bluair (more expensive but rock - I have a few) Coway Back up is box fan with hvac filter (check which one for smoke / etc. Good luck!

We run 3 in our house, one in the main living area (diy pc fan with hvac filters), and one in each bedroom (blue air brand or something, I think). Also consider plastic on leaky windows (cheap sliders).

I have a few Levoit the same size as this one. I don’t really care for them compared to the Winix and Blue Air ones I have.

Love mine too. We got 3 and they’re holding up better than the Blue Air’s I got.

I have terrible allergies and use Blue Air on every level. Works amazing.

You say costs don't matter, but what does that mean? There are devices for thousands of dollars out there, and you'd need multiple in a home. My general suggestion is to find a balance between *total cost* (initial, plus ongoing filters, plus electricity) so you can maximize the benefit and not feel pinched. Wirecutter previously did some studies on total costs - you can try to find them online, but it's been some years. If you really have no cost, just get the largest air purifier you can fit for each room and run it at the highest speed. Your home may feel like a wind tunnel, and that means it's working. For most people, Blue Air is a good balance in these various aspects. They are affordable up front, filters from the OEM aren't too bad (and generics are available on Amazon), and they have an outer washable filter (so you don't waste the expensive inner one on say, pet hair, etc.). If it were me, I'd get a large one for the room I sleep in, and at least one or two others. Ignore any automatic sensor based setting they offer. At night, or when you're in the room, you want it on the highest setting possible, and during the day, turn it down just one notch. You want the air flow to circulate and air to essentially be "scrubbed" by the filters. Remember this is only a secondary or tertiary method of cleaning in terms of priorities. Your best bang for your buck is washing your bedding weekly (including the comforter) in unscented detergent, vacuuming or sweeping, and having good airflow in your home to prevent dust and mold build up (leave bathroom and closet doors open). Use your A/C generously to keep humidity levels down in the humid months and for the sake of your sinuses, use a humidifier in the dry cold winter months if your climate has them.

I have a Blue Air and it works great. It definitely cut down on the dust in our bedroom. My kids have the Levoit purifiers in their college apartments. They must work because one daughter just asked if she could order some new filters because hers is dirty. The other said that something smells awful in the main room (that she shares with roommates), but she can’t smell anything in her room.

We have multiple Blue Air and a Coway. Happy with all of them. Frequently available on sale.

Second the Blue Air ones It’s been great to have going the last few weeks

Blue Air, there is the internal filter that’s replaceable and out filter that is washable. They come in many sizes. I have them all over the house and it’s majorly helped w allergies and dog smell

I have 3 diff sizes and I bought according to the sq foot reccs

It's absolutely worth it, especially if you have an open top cage. I use a Blue Air and it's fantastic in keeping the farm smell to a minimum. I also open my windows at least once a week and turn on all the fans for an hour to cycle in fresh air.

BluAir (Swedish) is what we used in the middle east.
