About this item
Product details
The Filterbuy replacement air filter 18x30x1 (actual size: 17.75" x 29.75" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 11 synthetic media (comparable with Micro Allergen Defense MPR 1200 & FPR 7) is recommended if you have pets or allergies with its capability to trap 95% of dust particles while protecting your home or business from smoke, smog, lint, pollen, mold, dander, and other forms of debris without impacting air flow. High quality construction features an electrostatically charged design with 14 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models (replace every 90 days for best results). Plus, our industrial grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit and withstand exposure to moisture. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality.

This filter size is hard
This filter size is hard to find. We went to several stores and could not find them. Was glad to find it at Filterbuy. Quality is great.

4 out of 5 stars review
not my first buy
These filters seem to be about an 1/8th of an inch smaller than previous purchases. That causes them to bang up when the a/c comes on and bang falling when goes off. Lastly, one of the shipments took seven days to arrive. FE was having some kind of hiccup.
