§ The Method
Use. Wash. Reuse.
§ 02— Let it work.
Let it work
MERV-8 microfiber captures dust, dander, and pollen — with the same airflow as a fresh disposable, every day.
§ 03— Unzip and wash.
Unzip and wash
Every 3 months, unzip the microfiber sleeve from the metal frame and toss it in the washer on cold delicate. The sleeve is dryer-safe. Each kit ships with 3 sleeves so you always have a clean one ready while another is in the wash.
It's the smallest change you'll ever make at home — and the one that pays you back the most over the next ten years.

Amélie R.Condo owner · Montréal
★★★★★
✓ Verified“The math alone made me do it. Paid for itself before the third wash.”
DK
David K.Homeowner · Toronto
★★★★★
✓ Verified“I manage 34 rental units. Switched them all. My HVAC maintenance calls dropped to zero.”
PS
Priya S.Property mgr · Vancouver
★★★★★
✓ Verified“Bought one for my parents and one for myself. Two years in, both still look brand new after a rinse.”
ML
Marc L.Homeowner · Quebec City
★★★★★
✓ Verified“I'm allergic to dust and the air in my place noticeably feels cleaner. No exaggeration — sleeping better.”
SJ
Sarah J.Renter · Halifax
★★★★★
✓ Verified“Fits perfectly in my 20×20 vent. Snapped in, done. The packaging was minimal which I appreciated.”
TG
Tomás G.Homeowner · Calgary
★★★★★
✓ Verified“Honestly skeptical at first. But the 10-year warranty sold me. No regrets — it's just one less thing to remember to buy.”
HM
Heather M.Condo owner · Ottawa
★★★★★
✓ Verified“My wife rolled her eyes when I ordered it. Now her sister has one. So does the neighbour upstairs. So it goes.”
LD
Luc D.Homeowner · Sherbrooke
★★★★★
✓ Verified“Twenty minutes in the washer beats a Saturday trip to Canadian Tire. That's basically the whole pitch for me.”
JW
Jasmine W.Renter · Edmonton
★★★★★
✓ Verified“Property manager for an 80-unit building. The cost analysis was a no-brainer. Tenants haven't even noticed the change.”
RF
Robert F.Property mgr · Mississauga
★★★★★
✓ Verified“Worried it would restrict airflow but it's been totally fine. Furnace runs the same, my bills haven't changed.”
NP
Nadia P.Homeowner · Winnipeg
★★★★★
✓ Verified“Two and a half years in. Frame's still rock solid and the sleeves come out of the wash looking new. That's it, that's the review.”
BC
Brian C.Homeowner · Saskatoon
★★★★★
✓ Verified“Emailed about a weird non-standard vent size and got a reply with a measurement diagram the same morning. That's why I bought one.”
