Wish I knew about this product sooner!

This product works perfectly in my converted garage man cave/cigar lounge. After smoking cigars with friends, the next morning is like it never happened! Better air quality than any cigar bar that I've been to.

Overall Health Improvment

I have (2) two MinusA2 Ultra Quiet Air Purifiers, and there are no substitutes for this product. My daughter has asthma and I have pet allergies. We also have three (3) small hairy dogs. We had multiple air filters before that were noisy and very ineffective. The first day ( overnight ) after installing in my daughters' room there was not a hint of dog odor. She slept sound ( the other air filter she said was too noisy, and she concentrated on the hum, and it kept her awake) The one in my living space is incredible. Tightness in the chest , gone. Itchy nose and eyes, gone. Price is not even a discussion. You can not put a price on the overall health benefits you receive for this. My daughter has stopped the daily use of her inhaler! Fewer trips to the doctor's office. I don't keep purchase as much over the counter allergy meds. Again Priceless!

It’s amazing. I sleep with 3 dogs. I’ve woken up with heavy phlegm in the back of my throat every morning. The first night, and every night since, I wake up with a clear throat

The most amazingly quiet effective air purifier.

We're up to 3 MinusA2 air purifiers - love 'em

We originally purchased two MinusA2 air purifiers via Amazon, for use in our home offices, and over the last month they made a huge difference. The main reason for the purchase of the first two was because my spouse and I were both suffering horrific bad seasonal allergies due to junipers and other pollen-producers in our area. However, our house is rather larger than just those two repurposed bedrooms-into-offices, so if we were happy with the 1st two units, we thought maybe we would buy a third for the rest of the place. (Still not quite up to the full square footage of the house, but close enough.) Anyway, the allergies abated to the point where we could tell immediately the difference when we went outside for any length of time. On top of this, after dusting and vacuuming, the re-accumulation of house dust is a fraction of what it was. Very, very happy with these RabbitAir purifiers, and plan to join the 'yearly filter replacement subscription' as soon as RabbitAir runs a promotion for that again. For now, the new 3rd purifier will probably be moved between the master bedroom and the rest of the house as needed. Pros: - Excellent filtration, positive effects evident within a couple days - Really nice looking filter design, very modern. (For our 3rd RA MinusA2, we got the Starry Night cover, other two are just white.) - Super quiet most of the time...except when it needs to be a tad noisier to do its job - Filter replacement costs quite competitive compared to other high-end purifier systems - Fast delivery from RabbitAir, well-packaged boxes - Pretty good controls selection - South Korean manufacturing, not Chinese Cons: - Wish there was more control over the mood light & sleep modes. What I would really like is the ability to have the purifier run at automatic speeds, but also be able to keep the mood light, the air purity indicator and the control lights on regardless whether the room is dark or not. In other words, to be able to fully disable sleep mode. - Yes, this is a pricey air purifier, but after trying -- and having zero results -- with the sub-$100 and even $150 purifiers, it's clear you get what you pay for. Tip: - If the purifier seems in auto/pollen mode to be running fast a lot of the time, clean the pre-filter and also especially the little air quality sensors. The one in my office seemed to be doing that last week, running a lot a medium speed and no slower. After checking, I found a fair amount of dust right at the sensor, especially around the intake vents. Following the instructions, I cleaned the whole area & the sensor using a moistened q-tip, dried it, and everything was copacetic again.
