It’s a little spendy, but I got [this](https://www.homedepot.com/p/Honeywell-PowerPlus-HEPA-Air-Purifier-Extra-Large-Room-530-sq-ft-Black-HPA3300BV1/312232605HoneywellPowerPlusHEPAAirPurifier,Extra-LargeRoom(530sq.ft.)BlackHPA3300BV1-TheHomeDepot) air purifier with a HEPA filter when doing renovations in my older home. It works well on days like this, and also helps overall with my allergies.
I have 5k Honeywell v1. Works very well in my room (10"11 ft) . It don't have aqi Monitor so I need to turn on. But just 11W isn't bad imo
I have both and have been using them for the last month. Both are nice and work well. The V1 is suited for smaller rooms. I found it works well for rooms smaller than 200sqft. Also if you don't have air tight rooms or a room near a balcony, the V1 struggles. If you have a larger room or like to keep the window/balcony door slightly ajar, then the V5 is much better. It also has app integration and a pm2.5 display. If you have the money, get the V5. Otherwise the V1 also works great. If your room is quite air tight, then there is very little difference in their performance.
I’ve tried a few and the germ guardians are the best bang/buck. The big Honeywell ones if you have to do a BIG space. We have a Dyson and I don’t love it.
Yes. I have Honeywell HEPA units in multiple houses. 24/7.
Honeywell. Their HEPA air purifiers routinely test out as the most effective and they make units made for spaces that large (I have one, it's such a relief during wildfire season). They aren't the quietist or the prettiest, but they don't need to be because they work. If you'll allow me on my soap box just a sec, please don't spend your money on popular "technologies" like ozone, static electricity, magnetized, etc. They don't work. What works is certified HEPA filters, H13 or H14.
