We love being able to provide a service that helps keep our community healthy. The MERV (Minimum Efficiency Reporting Value) rating is a measure of a filter's ability to trap particles, with a scale from 1 to 20. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, capturing 90% of airborne particles. MERV 11 filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers, capturing 95% of airborne particles. MERV 13 filters are perfect for larger homes or businesses, and those who want the best possible filtration experience, capturing 98% of airborne particles.

We also offer MERV 8 air filters with activated carbon, which are perfect for homes or businesses that want to inhibit unpleasant smells while providing reliable MERV 8 quality filtration.

Choosing the right filter size is important. The nominal size is a shorthand number rounded to the nearest whole or half inch, while the actual size is the filter's precise dimensions. To find the right size, measure your current filter and round up to the nearest inch.

Replacing your air filter regularly is crucial for maintaining a healthy lifestyle. Breathing dirty air can lead to the development of asthma, allergies, and other respiratory issues. We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean.

At Filterbuy, we are committed to providing better air for all. We believe that everyone deserves to breathe clean, fresh air, and we work tirelessly to ensure that you, your family, and your community have access to the best possible indoor air quality. Our new, green-framed filters symbolize the peace of mind that comes from knowing your home or business is being properly cared for.
