Pretty good. It's just a little louder than I expected

It works as expected. A good unit.

My feedback per your request.

Aesthetically, the unit is great. I really like the looks and design of the unit compared to other brands. Performance wise, I am very disappointed. I bought this unit with the sole purpose of eliminating cigarette smoke and odor. I use this unit in my "man cave". My wife complains about the cigarette smoke coming upstairs from my man cave. This unit does little to nothing about this issue. I feel that I have wasted $500.00 as this unit does nothing in regards to my needs. It was advertised as very good for smoke but it makes very little if any difference. I don't imagine you offer any kind of buy back plan or any other offers to un-happy customers do you


Rabbit Air

Hello David, Thank you for your feedback. We have a number of customers who use our air purifiers to remove smoke from cigarettes and cigars, and our air purifiers are even used in a number of cigar lounges and shops across the country.  Although smoke is a difficult pollutant to remove, when used properly our air purifiers can significantly reduce it in your home.

If you don't mind, we have a few tips that may assist you in helping clean your air. we definitely recommend placing it at least 4 feet above the ground as smoke tends to rise, so you will want your air purifier higher up to more quickly trap the particles before they have time to spread.

As far as placement of the air purifier, in addition to keeping it elevated, the MinusA2 should be placed in the room that you prefer to smoke in, and as close to where you smoke as is comfortable.  The MinusA2 works best in rooms that are about 300 square feet or less, and for the best removal of cigar or cigarette smoke we recommend operating it on a manual High speed while you are smoking, and leaving it running for at least a couple of hours afterward so that the air purifier is able to trap any residual odors. We also recommend closing any ventilations as smoke may still drift into other rooms. 

We're sorry to hear that you're unhappy with your air purifier, and wanted to give a friendly reminder that there is a 90 day money-back guarantee. You are always welcome to contact us if you have any questions!

Kind Regards,

Rabbit Air

Nice Machine

I love the air condition indicators, and they are pretty accurate. What a great product. Maybe give us an option to buy the product without the white/blue strip light on the panel will be even better. I personally wanted it all black with the rabbit logo only. The lights to me services no purpose as I have night lights at home. I think a complete black panel will look clean and simple. Different people have different feeling, that's why it will be great to give customers a choice to pick a panel with, or without the lights. Thanks
