We love being able to provide a service that helps keep our community healthy. We offer a range of filter options, including 20x20x1, 16x25x1, and 20x25x1 air filters, as well as 20x25x5 Honeywell air filters.

Understanding the Measurement System: - Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. - MERV 8 air filters provide standard protection, capturing 90% of airborne particles, and are perfect for almost any home or business. - MERV 11 air filters provide superior protection, capturing 95% of airborne particles, and are ideal for homes or businesses with pets, smokers, or allergy sufferers. - MERV 13 air filters provide optimal protection, capturing 98% of airborne particles, and are perfect for larger homes or businesses, or those who want the best possible filtration experience. - MERV 8 air filters with activated carbon provide odor elimination, inhibiting unpleasant smells while maintaining reliable MERV 8 quality.

We believe that everyone deserves to breathe clean, healthy air, which is why we work hard to ensure our customers have access to the perfect air filters for their needs. Our commitment to quality, convenience, and community sets us apart, and we're proud to be a part of improving indoor air quality across the country.
