The 18x20x1 Carter MERV 8 Washable Electrostatic HVAC & Furnace Air Filter: A Comprehensive Review


When it comes to indoor air quality, having a reliable air filter is paramount. With so many HVAC and furnace filters in the market, it can be challenging to select one that offers optimal performance. One of the leading air filters on the market is the 18x20x1 Carter MERV 8 Washable Electrostatic HVAC & Furnace Air Filter. In this review, we’ll take a closer look at this air filter’s features, how it works, and why it may be an excellent choice for your home or office setup.

Key Features

The Carter MERV 8 air filter is laden with various features that make it an excellent fit for indoor air quality enhancement. To start, it has a lifetime warranty, promising a long service life, and durability. It’s washable, which means it doesn’t need frequent replacements like disposable filters. Also, it’s made from robust and high-quality materials, ensuring optimal functionality over an extended period.

The MERV 8 rating qualifies it as a mid-level filter that’s capable of trapping various pollutants that cause allergies, respiratory illnesses, and other health issues. With a MERV 8 rating, it can capture larger particles such as pollen, pet dander, and dust mites, and smaller airborne particles such as mold spores, bacteria, and viruses. Its electrostatic feature means it uses static electricity to attract and trap airborne particles.

Design & Construction

The Carter MERV 8 is a pleated air filter measuring 18x20x1 inches. The pleats are deep and trap more particles as air passes through them. Moreover, the air filter has a metal frame, adding to its durability and longevity. The frame is also coated with a resistant layer, protecting it against rust and corrosion.

The filter element is made from high-quality materials that improve its electrostatic attraction capabilities. These materials are also washable, which makes cleaning and maintenance easier. Overall, the filter’s construction and design make it a sturdy, reliable, and long-lasting air filter.


The Carter MERV 8 air filter’s performance is impressive, and it has several noteworthy benefits. First, its MERV 8 rating guarantees excellent indoor air quality results. It traps more than 90% of airborne pollutants, ensuring that the air in your home or office is free from allergens and airborne particles that can harm your health.

Additionally, the filter’s electrostatic feature enhances its air filtration capabilities by trapping more particles than non-electrostatic filters. The electrostatic feature allows the filter to maintain its trapping ability even when it becomes dirty, unlike some conventional filters that trap less as they accumulate impurities.


Maintenance of the Carter MERV 8 air filter is effortless and straightforward. You can either wash it using water or vacuum it gently to remove any impurities. It’s advisable to clean the filter every three months, depending on the environmental conditions surrounding your home or office. The filter is washable, which means you don’t have to replace it frequently like disposable filters. Consequently, it’s an economical option that saves you money in the long run.


Installing the Carter MERV 8 is a hassle-free process that you can do yourself. You only need to follow the manufacturer’s installation instructions, and you’re good to go. However, if you’re unsure about the installation process, it’s best to seek assistance from an HVAC technician.
