## Overview

Filterbuy’s 13x20x1 MERV 13 air filters deliver hospital-grade filtration by capturing 98% of airborne particles including allergens, smoke, and bacteria. Featuring electrostatically charged pleats that last three times longer than standard fiberglass filters, these durable, easy-to-install filters fit universally in HVAC systems. Constructed with industrial-grade frames and dual wire backing, they withstand temperatures up to 200°F and moisture exposure. Proudly made in the USA with recyclable materials, they offer a sustainable, high-performance solution for healthier indoor air.

## Description

The Filterbuy replacement air filter 13x20x1 (actual size: 12.88" x 19.88" 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 13 synthetic media (comparable with Healthy Living Ultimate Allergen Defense MPR 1900 & FPR 10) is recommended if you have a respiratory illness (such as asthma) with its capability to trap 98% of dust particles while protecting your home or business from bacteria, smoke, smog, lint, pollen, mold, dander, and other forms of debris without impacting air flow. High quality construction features an electrostatically charged design with 16 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.

Review: Good product - I taped a single Merve13 filter to a 20" fan to build a free standing air filter. I also taped four, 5" X 20" X 20" Merv 13 together with a 20" fan to build a second free standing unit. Both cleaned the air in my 2,400 square foot house after a few minutes - checked it out with an air quality meter. Not much 'cleaning' difference in the two except the 5" one with a much greater filter area will last much longer before it needs to be replaced. I have a 5' filter in my furnace as well and change it every 6 months, but it probably would easily last a year. After 6-months there is only very little residue on the filter.
Review: They work great! - These work great! and a good price.

These work great! and a good price.

### ⭐⭐⭐⭐⭐ they fit perfectly
*by S***L on 16 December 2025*

My hvac uses the 14x24x1 filter size. Every other brand I would buy, did not fit correctly. I had to bend the corners to fit it in. But these are slightly smaller, and they fit perfectly.
