## 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.

### ⭐⭐⭐⭐⭐ Great Quality, Perfect Fit, and Value for Money!
*by A***O on June 16, 2025*

I’m very satisfied with these 16x24x1 replacement air filters. They fit perfectly in my HVAC system and are incredibly easy to install. The lightweight design makes handling and swapping them out hassle-free, and the sturdy frame holds up well without bending or warping like some cheaper options I’ve tried before.The MERV 8 synthetic media does a great job trapping dust, pollen, and other particles without restricting airflow, and I’ve definitely noticed a difference in the air quality at home. Plus, the filters last much longer than basic fiberglass types, making this a great value for money purchase. I’ll absolutely continue buying these and would highly recommend them to anyone looking for reliable, high-quality air filters!

*by D***  on June 15, 2025*

It’s very hard to find my size filters in the stores. These are well built filters that seems to do a great job filtering. Slid right into our air handler no problem and are holding up well. Very happy for the price getting ready to order more.

### ⭐⭐⭐⭐⭐ great filter for the home
*by A***3 on June 7, 2025*

I have purchased this brand for my home for the last 5yrs. they are good quality, the price is a bit high. they do come in a pack of 4 so that is nice because I can go 4-5 months with out a purchase. I did catch the amazon deal/sale. so that helped. But yes recommend
