Description
The Reusable MERV 4 Foam Air Filter is a prominent choice in the industrial HVAC filters range, specifically designed to cater to the demands of commercial HVAC systems. This filter type holds a unique spot because of its distinctive characteristics that ensure efficient filtration while offering an environmentally-friendly, reusable feature.
The term “MERV 4” denotes a specific degree of air filtration efficacy, as per the Minimum Efficiency Reporting Value (MERV) scale. This rating system, governed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), ranges from 1 to 16. With a MERV 4 rating, this reusable foam air filter is designed to trap particles as small as 10.0–3.0 µm in size, which typically include dust mites, mold spores, and pollen. Though not designed for eliminating smaller, micron-level particulates like certain allergens, tobacco smoke, or bacteria, MERV 4 filters are perfectly adequate for the industrial and commercial environments where fine particulate filtration is not a prime concern.
The construction of the Reusable MERV 4 Foam Air Filter is truly what sets it apart. Made from specially engineered foam, this filter features an open cell polyurethane design, allowing for exceptional airflow and minimal restriction. The foam is durable yet flexible, facilitating easy installation and removal.
An advantage of this filter is its reusable nature. It can be cleaned and reused multiple times, drastically cutting down the costs associated with frequent replacements. To clean, simply remove the filter, rinse it with a mild detergent solution, let it dry, and reinstall it. This process is not only cost-effective but also an environmentally responsible choice.
Our standard MERV 4 filters come in the most popular sizes and our “Easy CustomsSM“ is the most user friendly way to buy a custom size filter exclusively for your particular needs.
This type of filter is ideal for systems and conditions where high-level particle removal is not needed but cost and environmental considerations are significant. Its sustainability, affordability, and effectiveness make the Reusable MERV 4 Foam Air Filter a go-to choice for many commercial buyers.
