## Overview

Filterbuy’s 16x21x1 MERV 8 pleated air filters deliver high-efficiency filtration by capturing 90% of airborne particles while maintaining optimal airflow. Featuring electrostatically charged synthetic media and durable industrial-grade frames with dual wire backing, these filters last three times longer than standard fiberglass models.

## Description

The Filterbuy replacement air filter 16x21x1 (actual measurements: 15.50" x 20.50" 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 8 synthetic media (comparable with Clean Living Dust Defense MPR 600 & FPR 5) is recommended in most scenarios due to its capability to trap 90% of airborne particles, protecting your home or business from debris, lint, pollen, mold, dander, and other forms of dust 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. 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.

Review: Exactly what I needed and arrived early. The reason for the 4-star rating is due to bad experience with UPS and not the seller. Item didn’t arrive via UPS truck and the delivery person proceeded to throw my package up the stairs. Proof of delivery photo was the inside of their vehicle.
Review: Yes, fit perfect and excellent quality.

## Questions & Answers

**Q: When should I change my air filter?**
A: We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc.

**Q: Will these air filters fit my system?**
A: Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size. But if you see a specific brand name on a listing, make sure it matches your unit model.

**Q: How many air filters do I need?**
A: This varies for every customer depending on specific needs such as the number of vents in your home. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.

**Q: How do I change my air filter?**
A: After finding the right size, turn off the power supply and remove the cover from your intake vent before taking out the old filter. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.
