Buy 25x28x1 Air Filters Online

Custom Filters Direct 25x28x1 air filters are one of the important parts of your home’s HVAC system. Our air filters are designed to effectively remove harmful particles from the air and ensure you and your family breathe clean, fresh air and stay healthier.

Unlike other ordinary air filters, our AC and furnace air filters use 100% synthetic media to remove more than 90% of the airborne particles and other bacteria that trigger health problems. Additionally, they remove dust, pollen, and other allergens from the air and make it easier for your heating system to work efficiently.

When used regularly, air filters can become dirty, which can lead to health problems. To keep your air filters running smoothly, you should change your air filter every 60-90 days. If you have allergies or asthma, it’s even more important to replace your filter regularly. Air filters remove tiny particles from the air that can trigger an allergic reaction. Replacing your filter is also a good way to keep your indoor air clean and fresh. By removing dirt and dust from the air, you’ll be less likely to get sick.

Select the Right MERV Rating
