AIO about air quality

Hey, I live in a studio apt sized space and like to cook meats on high heat. I have a Honeywell hepa air purifier hpa300 that on the higher fan speeds will absolutely suck all the smoke created in a matter of seconds. I can’t speak on its ability to reduce particles I don’t have a meter or anything

Taking my friends computer apat to try and fix....... this shit is nasty af. The whole computer is Like this....fml

Yep, that will do it Make him clean it or buy a replacement. I would recommend vacuum or compressed air, preferably outside. The dust bunnies from lint and smoke residue are prone to smear, stain, and stick. In the future... PC should be raised above floor, and optimally close to an air purifier. I

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

Air purifier for nursery?

I have 2 Honeywell HPA300 series purifiers in the house that I like! I keep them on low and the nose isn't very noticeable. On the higher settings it can be kinda noisy, but in a white noise way (I set it on high in the bedroom for the 4th to help reduce the sound of fireworks)

Tired of seeing 'just get a Coway' when someone asks for best home air purifier so here's an actual breakdown

One thing I’d add is noise tolerance. Some are just too noisy to handle like Honeywell HPA300

Should I call the health department

If you think that will help, then do it. It probably won't cause problems for you, but I think management might already be doing everything that's their legal responsibility. Outside looking in, I would expect them to be gone within about 3 months. That's how I would take "soon". I think you need to

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. It saved my ass when the mold was at its worst. The last few years I haven't used filters much (my home d

Dust allergy and affordable air purifiers? What’s the verdict?

I've had two cheaper ones, like the IKEA one, and honestly, they didn't do much for my hayfever. I think for air purifiers you need to get a good quality one, which can be a bit more expensive. Some good ones that I've heard of: - Honeywell HPA300 - Levoit Core 600S

Basement

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
