Frequently Asked Questions
Everything you need to know about keeping your home air and water pure.
How do I know which filter size is right for my HVAC system?
The easiest way is to check the label on your current filter. If the label is missing, measure the length, width, and depth of the intake slot. We recommend matching the 'nominal size' printed on most standard filters for a perfect fit.
How often should I replace my home air filters?
For optimal air quality, we recommend replacing standard 1-inch to 2-inch filters every 90 days. If you have pets, allergies, or live in a dusty environment, you may want to replace them every 60 days.
What is your return policy if I order the wrong size?
We offer a 30-day hassle-free return policy. If you ordered the wrong size, simply contact our support team to initiate a return or exchange. Please ensure the filters are unused and in their original packaging.
Do you offer subscription services for automatic deliveries?
Yes! You can choose our 'Subscribe & Save' option on any product page to receive automatic deliveries at your preferred interval, ensuring you never breathe dirty air again while saving on every order.
