Customer Testimonials
Life-changing for my daughter with asthma. We installed these in her bedroom and playroom, and her nighttime coughing has decreased dramatically. The pediatrician even noticed improvement in her breathing. We now replace filters monthly religiously – it is the best $20/month we spend for her health.
– Jennifer M., Portland, OR (Mother of 8-year-old with asthma)
I cannot believe the difference in dust accumulation. We used to dust furniture near vents twice a week – now maybe once a month. And my seasonal allergies are noticeably better when I am at home. The filter replacement is super easy, takes 30 seconds. Wish I had found these years ago.
– Robert T., Atlanta, GA (Allergy sufferer)
We have two cats and my husband is allergic. These filters in the bedroom have been a marriage-saver! He can actually breathe at night now. We still have the cats (obviously), but the constant sneezing and congestion is gone. The filters definitely catch pet hair – you can see it when you replace them monthly.
– Sandra K., Chicago, IL (Pet owner)
As a property manager, tenants with allergies always complained about air quality. These covers have been perfect – affordable enough to install in multiple units, and the health benefit keeps tenants happy and renewing leases. I stock replacement filters and sell them at cost. Total game-changer for tenant satisfaction.
– Patricia L., Denver, CO (Property Manager, 40 units)
My son has severe dust mite allergies. His allergist recommended covering vents in his bedroom. These filter covers have made such a difference – his morning congestion is almost gone. The investment in monthly filters is nothing compared to what we used to spend on allergy medications.
