Aerostar 21 1/2 x 23 5/16 x 1 MERV 13 Pleated Air Filter, 4 Pack

Our Ultimate Allergen Filter is designed to proactively capture even the most microscopic particles from the air, making it suitable for those who suffer from asthma and allergies. Classified as a MERV 13 filter, it effectively reduces allergy and asthma triggers by trapping unwanted allergens such as pollen, bacteria, and harmful virus carriers within your home's air.

At Aerostar, our approach is simple: to produce quality products at accessible prices. We believe that clean, healthy indoor air is a necessity in every home or place of business, but it should not come at a premium cost. Our filters efficiently remove a wide range of airborne contaminants, including lint, dust mites, mold spores, pollen, pet dander, smoke, bacteria, and viruses.

Each filter is meticulously crafted in the USA, inspected, and hand-stamped with MERV labels before being shipped to you in durable, damage-resistant containers. Our packaging is designed to be practical, without any additional plastic or promotional materials – just the high-quality filters you need. You can even reuse the box to store extra filters until you're ready for your next replacement.

By eliminating unnecessary packaging and shipping materials, we've significantly reduced excess waste, allowing you to enjoy a more sustainable and environmentally-friendly experience. Your home or business can be more energy-efficient with the right air filter for your HVAC system, and regular filter changes (every 60-90 days, or more frequently during peak seasons) can help prevent an overworked and strained system.

Aerostar's MERV-rated pleated filters, available in MERV 8, MERV 11, and MERV 13 configurations, are designed to meet the specific needs of your indoor air quality requirements. Whether you're looking to capture larger particles like lint and dust mites or targeting finer contaminants like smoke and bacteria, we have a solution that will keep your air fresher and healthier.

Manufactured in the USA by Filtration Group, a world-leading provider of filtration solutions, our filters are built to the highest standards of quality and efficiency. By choosing Aerostar, you're making a cost-effective step towards a cleaner, safer, and more productive indoor environment for you and your loved ones.
