When it comes to air filters, the size of the filter is an important factor to consider. While a 4-inch thick filter is more efficient than a 1-inch filter, the correct size depends on the oven. If you measure the filter slot and it's large enough to accommodate the thicker filter, you can use it. However, if the slot is less than 4 inches wide, you'll need to use that thickness.
To answer the question concisely, a 4-inch filter is usually the best option.These thicker filters have been proven to provide better air quality and will last longer. 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 a pet, you'll be especially interested to know what type of filter will help you keep the air clean and free of this particular pollutant. We've mentioned before that a filter with a greater depth won't need to be changed as often as a thinner one, so keep this in mind when deciding between different HVAC filter options.We recommend that you buy the best air filter you can afford once you've looked at all the other factors.
At the same time, a thicker filter is less restrictive and will allow better flow of purified air. A 1-inch filter with less surface space will clog up fairly quickly and will need to be replaced much sooner than a coarser filter. 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.Not only will the thickness of the air filter be important, but also the MERV rating of the filter. A 1-inch air filter should be changed approximately every 30 days, while a 4-inch filter can last 3 to 6 months.
If you forcibly place a 4-inch filter in a location intended for a 1-inch filter, air quality can be significantly affected. Some air conditioning specialists have also found that thicker filters are better at providing a perfect fit that prevents unfiltered air from passing through.A deeper depth can also improve filter life and efficiency; it also makes it easier for air to enter and exit the filter. To put that into perspective, a 1-inch air filter may need to be changed every month, while a 4-inch air filter can last up to six months. Pets, heavy traffic, and poor outdoor air quality can affect the frequency of filter changes.In conclusion, when selecting an air filter for your home or business, it's essential to consider both its thickness and MERV rating.
A 4-inch thick air filter is usually more efficient than a 1-inch thick one; however, if your oven slot is less than 4 inches wide, then you'll need to use that thickness. Additionally, make sure to buy an air filter with the best MERV rating you can afford in order to ensure optimal air quality.
