The Environmental Protection Agency (EPA) states that MERV 6 is the level that begins to protect air quality, so MERV 8 is a good minimum level for an air filter if you want to start protecting air quality. A minimum of MERV 11 is generally recommended for allergy sufferers. MERV 13 is often found in high-end homes, hospital common areas, and high-end commercial buildings that are LEED certified. A MERV 13 20x20x1 air filter is considered an excellent air filter for allergies.
The most intense air filters are between the MERV 14 and 20 values on the MERV scale. For that reason, these filters are often used in highly controlled environments, such as hospitals, operating rooms, laboratories and smoking rooms. Air filters come in a variety of materials, and selecting the best one for your home depends largely on whether you have pets, the type of climate you live in, respiratory conditions, and general household cleanliness. Understanding the characteristics and MERV rating of each material can help you select the best one for your home.
Selecting the right air filter size is vital for optimal energy efficiency and appliance performance. The size and material of the filters used in heating, ventilation and air conditioning (HVAC) systems have a significant impact on energy efficiency and pollution reduction. During a wildfire, you'll need to change your filters more often than you would under normal air conditions, and there are some indicators that can help you know when it's time to change them. You can use the MERV chart as an air filter comparison chart to find the best 16x25x1 HVAC filter.
The air filter can be placed in the return air duct or in the fan compartment before the return air reaches the air controller. You can also have a single whole-house filter, which can measure around 3 to 6 inches, located in a filter cabinet; it must be next to the boiler or air controller. Many homeowners assume that filter maintenance includes buying a new filter and changing it every few months, but there are a few things you can do to extend the life of the filter. MERV stands for Minimum Efficiency Reporting Value and measures how well a filter removes particulates from the air.
In areas with high air pollution, an air filter with quality components can make all the difference between a healthy and an unhealthy living environment. Typically, both sources offer the right size air filter for the system, while aftermarket manufacturers, such as FilterBuy, add additional features such as odor blocking, a higher MERV rating, and designs that are easier to replace. This is a list of the most popular filter brands on the market, with information directly from Filter King. A good air filter keeps the central air conditioner (and oven) working by protecting mechanical components from dust and dirt.
To determine the appropriate filter size, measure the existing filter or consult the manufacturer's specifications. We measure how well an air filter removes dust, pollen, and smoke from the air, and we check how freely the air flows through the filter at any fan speed. Additionally, it's important to check your filters regularly to ensure they're not clogged with dirt or debris.
