PowerPlus HEPA Air Purifier, Extra-Large Room (530 sq. ft.) Black HPA3300BV1

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.

Yes, an air purifier helps. The best brand is Honeywell with a HEPA filter. Second is Bionaire with True HEPA filter (purple one), third is Bionaire with the blue filter. Levoit kind of sucks. Don't waste your money on the Pure Enrichment Personal Air Purifier.

For reasonable VOC removal there are only 4 players I know in the market which offer products which have the minimum 10 pounds of sorbent media: Airpura, Allerair, Austin, IQAir. Wildfires product a huge mix of chemicals - from the vegetation, contents of burned buildings, etc. There is no consumer solution that removes all VOCs. Each type of media is better at some chemicals, not so good or not effective at all with others. For the same reason there is no sensor that I know that will give you the level of all VOCs. These machines and filters tend to be expensive. I just upgraded my Austin units with Immunity Machine filters which cost \~$700 each. We were spared wildfire smoke this season but with AQI numbers breaking 100 I was able to keep my indoor values close to 0. I use Austin and IQAir VOC machines along with Honeywell and Whirlpool HEPA units, 3 filters per room.
