Filterbuy 18x20x1 Air Filter MERV 8 Dust Defense (1-Pack)

Product Description Filterbuy proudly offers a comprehensive selection of air filters catered to meet diverse indoor air quality needs. Our filters are classified by Minimum Efficiency Reporting Value (MERV) ratings, which assess their ability to capture airborne particles on a scale of 1 to 20, with higher numbers indicating greater filtration efficiency.

Standard Protection (90% Airborne Particles): MERV 8 Air Filters Ideal for most residential and commercial spaces seeking reliable, cost-effective filtration, these MERV 8 filters trap common pollutants like dust, pollen, and lint while maintaining optimal airflow.

Superior Protection (95% Airborne Particles): MERV 11 Air Filters Designed for homes or businesses with added considerations like pets, smokers, or allergy sufferers, our MERV 11 filters provide enhanced capture of smaller airborne particles.

Optimal Protection (98% Airborne Particles): MERV 13 Air Filters For larger spaces or those requiring the highest level of filtration, our MERV 13 filters excel at trapping microscopic contaminants down to 0.3 microns, including bacteria.

Odor Eliminator (90% Airborne Particles): MERV 8 Filters with Activated Carbon Combining the reliable performance of MERV 8 with the odor-absorbing properties of activated carbon, these filters help neutralize unpleasant household smells.

Regardless of your specific needs, Filterbuy has you covered. All our air filters feature a pleated, electrostatically charged design for superior particle capture, reinforced beverage board frames for durability, and 100% American manufacturing. Additionally, our robust supply chain ensures we can swiftly deliver custom sizes directly to your door.

Why Change Your Air Filter? Regularly replacing air filters is essential for maintaining optimal HVAC system efficiency and indoor air quality. Dirty filters can restrict airflow, leading to higher energy costs and potential equipment damage. Moreover, breathing contaminated air raises health risks, contributing to conditions like asthma, allergies, and respiratory illnesses.

We generally recommend changing filters every 3 months, though frequency may vary based on factors like household size, pet ownership, and local environmental conditions.

Choosing the Right Filter Size Each of our filters has both a nominal size (the rounded measurement) and an actual size (the precise dimensions). When selecting a replacement, measure your existing filter or consult your HVAC system's specifications to find the perfect fit.

Simplify Filter Changes with Subscriptions To make staying on top of filter replacements easy, we offer a subscription service that delivers fresh filters on your schedule, along with discounted pricing.
