Don’t Just Take Our Word For It
Check out why people love Airdog"I've struggled with allergic rhinitis for years. That an a deviated septum keep me from sleeping well at night. I was sure that poor indoor air quality in my house was compounding the problem.I'm sleeping much better at night and am having to take much less allergy medication. I even bought a second unit to put in the front of the house.
"I bought this as a Christmas gift for a friend from India. They use a lot of spices and the smell lingers for a long time. They had dinner then went out and when they came back the smell was completely gone. They were very impressed with the unit."
"For the first time in a while, the kids don't wake in the morning all coughs and sneezes. We are no longer taking any allergy medication. ... Thanks to the X8, we are finally dealing with the cause and not just our symptoms."
"This is the best air filter I've had. I'm in love with it. ... Due to cat dandruff, I have a hard time breathing. It is hard for me to sleep at night but since getting the X5, I am sleeping all night now and breathing through my nose again."
"My family is breathing so much better inside now—no more coughing, we sleep better at night, and even the pets seem to be more comfortable now."
"My LIFE depends on this Airdog X3. I am 75 years old and was told I have numerous allergies and would be needing a sleep apnea machine. ... I am allergy- and pill-free, no need for a sleep apnea machine, all my tests are perfect. Most of all, I BREATHE the MOST BEAUTIFUL FRESH AIR possible."
