I Smoke Weed and I Kick My Cat Out of My Room When I Do, Is That Okay?

Honeywell makes some good air purifiers that are quiet and have a dimmer function for nighttime. A little more expensive, but reliable. I have an HPA200 and HPA 300 that have been running 24/7 for years.

What's the best air purifier for home you'll recommend buying now?

I've been running a Honeywell HPA300 for about 2 years now and it's honestly made a huge difference with dust in my bedroom. The thing's built like a tank and you can actually see the pre-filter getting nasty after a few weeks which shows it's doing its job. Only downside is it's a bit loud on the h

Has anyone tried this self made air purifier? They’re called Corsi Rosenthal box

Looks like enough money and trouble that I would just get a cheap hepa filter if it were me. I bought a Honeywell hpa300 iirc. It's ran perfectly for over ten years. Filters are cheap on Amazon.

Sadly air purifiers cannot help with radon and you will also need A LOT of plants to make a difference to your air - we wrote about it here https://housefresh.com/do-plants-clean-the-air/ If you still want an air purifier you can run in your basement and can help with particles and mild odors, then

What's the best air purifier or brand to buy for home currently that has HEPA filters?

Honeywell makes good air purifiers. They're manually controlled, so not a smart device, but I have 4 of them in my home running 24/7 and they have been going for 6 years without any problems. I bought the HPA300 model. They need regular prefilter changes, and annual hepa filter changes. The replacem

Honeywell U2 Air purifier:

No way to dim light? I would take it apart and disconnect the LED if possible. I have had good luck with my older HPA300 Honeywell. Still runs great after 8 years of continuous running in my office.
