When it comes to air filters, more is often better. A 4-medium air filter offers a longer lifespan than a 1-medium air filter, meaning fewer filter changes, less money spent, and greater comfort. 4-inch filters cover a higher range of MERV ratings and overlap slightly with 1-inch filters, with a minimum rating of 8.Higher ratings of up to 16 can control supermicropollutants, such as bacteria, viruses, and dust particles. A deeper depth can also improve filter life and efficiency; it also makes it easier for filter air to enter and exit.
Reducing the thickness by one inch shouldn't be a big problem; for example, you should be able to use a 4-inch filter instead of a 5-inch filter. At the same time, a thicker filter is less restrictive and will allow better flow of purified air. That said, the 1-inch filter may be too shallow, causing a loose fit that allows unfiltered air to enter the ducts.1-inch pleated air filters have higher MERV ratings for one simple reason: they have more surface area to trap particulates. If you forcibly place a 4-inch filter in a location intended for a 1-inch filter, air quality can be significantly affected.
Particularly vulnerable parts include the motor of the air controller or the oven fan, which works overtime to push and extract air through the dirty filter, and the heat pump or air conditioning compressor that are responsible for circulating the refrigerant between the outdoor and indoor units. But what if your oven's air filter compartment is only 3mm thick? In that case, the 1-inch oven filter is the better choice compared to the 4-inch filter; however, a 3-inch thick air filter is the better option. If you try to use a 4-inch-thick air filter for a system that's made for a 1-inch-thick filter, the efficiency will actually be worse. If you're considering a thicker air filter to improve air quality, it might be best to focus on the MERV rating. For example, if you have pets in your home, you'll be particularly interested in what type of filter will help you keep the air clean and free of this particular pollutant. As an expert in SEO, I can tell you that when it comes to air filters, more is often better. A 4-medium air filter offers many advantages over its 1-medium counterpart: longer lifespan, fewer filter changes, less money spent on replacements, and greater comfort.
4-inch filters cover a wider range of MERV ratings than 1-inch filters do; they also overlap slightly with 1-inch filters with a minimum rating of 8.Higher ratings of up to 16 can control supermicropollutants like bacteria, viruses, and dust particles. A deeper depth can also improve filter life and efficiency; it also makes it easier for filtered air to enter and exit without any restrictions. Reducing the thickness by one inch shouldn't be an issue; for instance, you should be able to use a 4-inch filter instead of a 5-inch one. On the other hand, if you try to use a 4-inch thick air filter for a system that's made for a 1-inch thick one, then efficiency will actually decrease.1-inch pleated air filters have higher MERV ratings because they have more surface area to trap particulates. If you try to place a 4-inch filter in an area intended for a 1-inch one, then air quality can suffer significantly.
Parts like the motor of the air controller or oven fan may work overtime trying to push and extract air through the dirty filter; likewise, heat pumps or AC compressors may struggle with circulating refrigerant between outdoor and indoor units. If your oven's air filter compartment is only 3mm thick then it's best to go with the 1-inch oven filter instead of the 4-inch one; however, if possible opt for a 3-inch thick one instead. When considering thicker filters to improve air quality, focus on their MERV rating - especially if you have pets in your home.
