Amazing I have had many air purifiers. This one by all means is the best. Well worth the price. I now have a quality machine that will last many years.👍👍 11/22/2021 Michael E. Filter Queen Defender This is the third unit that I have of the Defender. We have 3 smokers in our house and really need these to help with the air. These unis are undetectable to the ear on low and medium, but high is a little annoying so I keep them at the lowest level in our family room, but believe it or not I have it on high in the bedroom. I can certainly here the unit but I learned jyst to ignore it and now it doesn't bother my sleep but this did take some time. I think the units work great as long as you stick to a filter reacement program. 11/15/2021 Cindy D. Helped my family with allergies 11/14/2021 Anthony D. The Defender Air Purifier is a great addition to our home. We were so impressed with the machine that our daughter bought a unit for her rental home and she says that the odor and dust control has changed the quality of their life. We are a solid Filter Queen family and our two daughters and my twin sister all use Filter Queen vacuum cleaners as well as ourselves that range from 10 to 35 years old and none have needed to be replaced. Our experience with the vacuum cleaner led us to try the Defender Air Purifier and we are very content with our decision. You just cannot go wrong with ANY Filter Queen product!! 11/12/2021 Laura B. This is. Game changer. I have many different kinds of air cleaners in my home. This is by far the best one. 123 Defender Tech Specs Dimensions: 17.5" height x 12.25" diameter Weight: 12 pounds Speed Controls: 3 Air Outlet: 360° Pure Top Release Motor: Brushless high efficiency motor (100,000 hours expected life) 120V / 60Hz / 85W Amps: 0.90 (high) 0.43 (medium) 0.27 (low) Outlet: Standard 110/120 U.S. Outlet Plug: Polarized Type A Plug CSA Approved: Yes Decibels: High Speed — 65 decibels Medium Speed — 56 decibels Low Speed — 46 decibels Filtration Level: > 99.99% at 0.1 micron Bacterial Filtration Efficiency (BFE): 99.999% Warranty: Lifetime Perpetual Warranty Customer Service Shipping Policy Privacy Policy Safe Harbor Policy Acceptable Use Policy Consumer Protection Code of Conduct Contact Us 1 American Road, Ste 1250 Brooklyn, OH 44144 USA 1-800-344-1840 (USA) +1-440-846-7800 (Intl) 1-800-834-6850 (Canada) hello@filterqueen.com Careers College Work Full & Part Time Worldwide Opportunity Information Company News Product Reviews Testimonials Facts Not Fear Terms of Service Refund policy Facebook Twitter Pinterest YouTube © 2021, FilterQueen Use left/right arrows to navigate the slideshow or swipe left/right if using a mobile device
