HPA100

Levoit Core 300 is a good, quiet True HEPA pick for your 200 sq ft room and allergies. Coway AP-1512H and Honeywell HPA100 are both reliable with good airflow and long-term performance. Look for True HEPA and strong CADR, and avoid vague “HEPA-like” filters or ionizers that make ozone 👌

You are describing exactly why I didn’t buy some of the more popular models often recommended. I just got 2 Honeywell HPA300’s. They are simple, process a lot of air, and the noise is very tolerable. I run 2 of them on medium setting in my apartment all the time along with an HPA100 and HPA200 (those last two are older gen’s) In my observation, the larger units have a less annoying noise than the smaller ones. Even though the decibels might be the same on paper, the larger flow chamber has a lower pitch, less piercing noise. I’ve never had a different brand than Honeywell before and I’ve been considering branching out. But your post is exactly why I chose to go with them again.

Many air purifiers with HEPA filters (small crud) also include a prefilter (large crud) and optional charcoal filter (odors). I have a Honeywell Insight Series (model HPA100B) that I'm happy with. The HEPA filter is changed annually. Prefilter is every three months. I don't use the optional charcoal filter, but I'm guessing those are changed every three months, too. My son just bought an air filter that has a washable prefilter, but the HEPA filter has to be changed every six months. Don't know about the charcoal filter. You can get some recommendations by googling "rate air filters" or "compare air filters" or "best air filters 2025." I think the grooming advice is helpful. Same with the cleaning advice comments. If grooming or cleaning is too much, can you hire some help? A teenager may be willing to brush your dogs or do vacuuming.

I was wondering the same thing. I own two Honeywells, the HPA-100 and 200 that I got for free. They're discontinuing that line, but I just replaced one through eBay because I like them so much. Normally they're super quiet and move a ton of air. The best thing is that they both take the same filters so it's all interchangeable. I saw the new models, and they look sleek, but I didn't want anything with an app, and I wasn't sure if the parts were as good as the old ones.

Anything with plasma, airwave, ozone etc is toxic. You have to research each model. I have a basic HEPA Honeywell because of this.
