I have a couple! The AirMega 100 is the smallest I have and the air mega mighty ap-1512 is the biggest— I also have the air mega 160 which is a great midsize one if your space isn’t too big. https://cowaymega.com/products/mighty-ap-1512hh?

This is the answer for reasonably priced air purifiers and it’s been the same for years. I have 2, zero issues. Filters are fairly priced. https://a.co/d/hC0PLzP Coway AP-1512HH

I have been using the [Coway AirMega](https://amzn.to/49gjTgt) for years. It has also been [Wirecutter’s](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/) top pick for a long time.

[Coway](https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-White/dp/B01728NLRG) There's a black version as well. It's the best you're going to get for around $150 (usd). The replacement filters aren't insanely expensive, and are readily available. Put it on "mid" in terms of the fan, and it will do the thing somewhat silently. I have two, and I replace the filters every year. I have pets, I live very high in the mountains in a VERY dry climate, and have allergies. This is the one you want : ) p.s. Also, get a humidifier. Just a simple one from Vicks or some other off brand. Humidity in the air does wonders in terms of pollens. Basically you're putting water into the air, which reduces dust and all the other stuff that's not good for you.

Conway 1512HH, don't forget to take the plastic off the filters when you turn it on :)

As u/ankole_watusi said, if you have forced air, start with a good filter on your furnace. If like me that's not the case then: 1. HEPA vaccuum 2. HEPA purifier 3. Wash your bedding frequently (this is highly under rated) 4. If you have an air intake, filter it, I would say at least MERV 11. COWAY is routinely 1/3 off on Amazon. (Including right now, apparently, in Canada [https://www.amazon.ca/gp/aw/d/B01728NLRG](https://www.amazon.ca/gp/aw/d/B01728NLRG) I have been buying them for long enough (very dusty outdoors environment and a lot of houseplants) to know the build quality had gone down a bit - specifically on the 1512 - but functionality has not diminished. I also have 2 of the older tower model, and they work very well. In terms of ROI cleaning regularly with a HEPA filtered vaccuum has more of an impact. But far and away the best has been to do both. I also MERV 13 filter my air intake, but that's specific to my situation.

Coway mega. I have tried many. This is the best I have found. No need to use the ionic function. Seriously it is the best!!! I tried Austin air, levoit, all price points. The coway gets things out of the air. Just give it time. [https://a.co/d/09RvvaLI](https://a.co/d/09RvvaLI)

The [Coway Airmega AP-1512HH](https://a.co/d/jdwKlHe) has [intense smoke filters](https://a.co/d/1mUHfdz) and should be good for your space. You will probably need one per floor if you’ll be spending long periods of time there.

I highly recommend the Coway Airmega AP-1512HH, it’s currently on sale for $210 on Amazon. I’ve been using it for a few months now and it’s definitely the best I’ve used. It also has different filter kits for different uses (standard, allergen, smoke, and pet).
