Our MERV rating system rates the effectiveness of our filters on a scale of 1-20, with a higher rating indicating better performance. Our MERV 8 filters offer standard protection, perfect for homes or businesses that want great indoor air quality at a reasonable rate. Our MERV 11 filters provide superior protection, ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers. For optimal protection, our MERV 13 filters are perfect for larger homes or businesses that desire the best possible filtration experience. Lastly, our MERV 8 filters with activated carbon serve as odor eliminators, inhibiting unpleasant smells while ensuring reliable MERV 8 quality.

To select the correct filter size, it's important to understand the difference between nominal size and actual size. Nominal size is a rounded shorthand number, while actual size refers to the precise dimensions of the filter. To measure your air filter, use a tape measure to record the width, length, and depth. Round up these measurements to the nearest inch to find the corresponding nominal size, which will make your online search easier.

Regularly changing your air filter is crucial for maintaining a healthy lifestyle. Breathing dirty air can lead to respiratory ailments such as asthma and allergies. Additionally, old filters can cause system defects, resulting in unwanted expenses from energy costs and repairs. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean.

Most of our filters are universally compatible with furnaces, air conditioners, heat pumps, or HVAC systems. However, if you see a specific brand name on a listing, make sure it matches your unit's model.

The number of air filters you need depends on your specific needs and the number of vents in your home. Our selection includes package quantities ranging from 1 to 12 filters, ensuring we have you covered no matter the situation.

To change your air filter, turn off the power supply, remove the cover from your intake vent, and take out the old filter. Insert the new filter to match the direction of air flow, replace the cover, and turn the power back on.
