MinusA2

I have (2) rabbit air minusA2. They are wonderful. Run them 24/7 in the living room and master bed. Filters are replaced annually. Not the cheapest but you really get what you pay for when it comes to quality filters that are always running

I own a Rabbit A3 and Rabbit MinusA2. The A3 is a lot quieter but both perform well. I did a blind test with a friend and he said that the air seemed "lighter", which I had agreed with. 

We had a [Rabbit Air filter system](https://www.rabbitair.com/) when we were raising and showing bunnies. It was very quiet and really kept the dander and loose hair under control. Unfortunately I don't remember the model we had but it was wall mounted.

There has to be some way of removing the stuff from the air, whether it's a filter (annoying to replace, can be pricey) or electrostatic/ionizing (noisy in my experience and generates potentially harmful/irritating ozone). We use a [Rabbit-Air HEPA filter system](https://www.rabbitair.com/pages/choose-your-air-purifier) and have had one for years. It's quiet and pretty efficient even if the space is larger than the rated capacity for the filter. Yes, there is the annual expense of replacing the filter but that can be budgeted for and scheduled, we change ours on the spring equinox so it's easy to remember.

I didn’t bother with HomeKit for the one I got. It has enough sensors that it adjusts for speed automatically and will go into sleep mode automatically after a few minutes of darkness. The model I have is not wall mountable, but there is a similar model from RabbitAir that has a wall mount option. I’ve used those in some of our stores.

I’ve got a question for you! I have a bunch of Rabbit Airs (A2 and A3). They’re phenomenal, but expensive as hell. I’ve used some of the Levoits (mostly the smaller canister shaped ones) and I can tell they do not come close to the RAs. Is there anything you’d recommend below $300 that can match or outperform the A2 or A3? I’m trying to get one large unit for my girlfriend’s place (allergies are KILLING me!!). I’ve been doing a ton of reading and it’s overwhelming. I get nervous spending that kind of money without knowing what exactly I’ll end up getting quality wise. Edit: Wanted to add I’m open to used and buying new filters if there’s a badass model that sells cheaply used online or on eBay!

These really are the "buy it for life" ones. RabbitAir are amazing too, at least from a longevity standpoint. I bought my MinusA2 somewhere around 2010 or 2011 and it's still going strong today.

Seconding Rabbit Air. I have a Minus A2 with a VOC filter package that I need to vacuum weekly as it becomes caked with dog hair. I also have their entry level BioGS that’s now 18 years old and works flawlessly. They have excellent customer service too. I also have a Coway Amega, which works just fine in my little foyer, but it’s not as impressive as the Rabbit minus A2.
