QuietCare True HEPA Air Purifier 17000-S

Yeah, I found this purifier at my parents' house and was surprised that it still worked.

Brings back memories. Got rid of mine more than a decade ago. HEPA filters need to be replaced frequently. Exact timing depends on contamination levels, fan speed, and hours used. A good guess would be yearly although I have some huge filters that last 5 years. The 17000 series HEPA units were large and bulky. Filters were the same. Current models are much smaller, easier to move and change the filter.

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.

Honeywell we use the big 500 sq foot one for main floor and the smaller 200 sq ft one for the bedroom leave them on low change filters every 4/6 months

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.

Honeywell HEPA. Don't buy an electrostatic/ionizer type "purifier" as it creates O³ (ozone) - which is hazardous (and is also a component of smog).

Honeywell HEPA air purifiers. I have two: one in bedroom and one in the room where I spend most of my time watching TV, etc. Makes a difference for me.

I have these, as well, and they’re great. The cheap after-market filters from Amazon work perfectly for them, too.

They aren't trendy or cool, but we've had a good experience with the honeywell HEPA air purifiers. They have different options from $80 up to $250 depending on size and features.

👍Honeywell HEPA air purifiers is what we use for our trove of critters. Easy to swap the filters and has a “quiet” energy saving mode that makes very little noise so not to upset small ears. But they work really well I can contest to that lol. When i change the filters in our home it’s like a rug of small animal hairs 😂we run a large model in our living room and a smaller unit in our tv room.
