Review: Does the job - These are reasonably priced compared to the big box stores and seem to be of similar quality.
Review: Merv 13 - These filters are the best made filters I have found to date. Sharp folds, tight construction. They filter so well that I had to tape them, otherwise they are vacuumed by my Carrier system. Unfortunately, filter housings are very poorly designed in most AC systems. By blue taping the filters you prevent any filtering loss that will happen with most systems. Air quality has improved by a huge massive lot vs Merv 8 that I was using. These Merv 13 even help with fumes and cooking smells. I have some serious allergies and these filters are definitely a game changer for those who spend more time at home. I feel soo much better. Extremely happy with the change and the filtration capabilities. I have noticed no change in my carrier system performance whatsoever. I'm sure it is harder for the blower motor to use merv 13 filters, but my AC handles it perfectly. Merv 13 could be too much for some older AC systems, so always consider check your model and capabilities of it. My AC is purposely undersized. I run my AC for about 10 to 15 hours a day during the long Central FL summers. You can see how the new vs old looks in the picture after a hard month of use. If you can, get these, you will love them.

## Questions & Answers

**Q: Why should I change my air filter?**
A: To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs.

**Q: When should I change my air filter?**
A: We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc.

**Q: Will these air filters fit my system?**
A: Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size. But if you see a specific brand name on a listing, make sure it matches your unit model.

**Q: How many air filters do I need?**
A: This varies for every customer depending on specific needs such as the number of vents in your home. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.

**Q: How do I change my air filter?**
A: After finding the right size, turn off the power supply and remove the cover from your intake vent before taking out the old filter. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.
