As the filter traps more dirt, dust, and allergens from the air, the efficiency of the filter decreases. To ensure your air filter is working properly, it's important to know how often you should check and replace it. A general rule of thumb for pleated air filters (such as those made by FilterBuy) is to change them every 90 days. However, there are some factors that can shorten or extend the time between oven filter replacement intervals.
The basic consensus among HVAC professionals is that the furnace filter should be replaced every 90 days or every three months. This depends on the thickness of the filter. Thicker filters have more room to accumulate dirt and dust, so you don't need to change them as often. Thomas & Galbraith Heating, Cooling and Plumbing, of Ohio, recommends changing filters less than 2 inches thick every 30 to 90 days.
Three- or 4-inch filters can last 6 to 9 months, and filters up to 6 inches thick can be replaced once a year. To prevent dirt or debris from entering a system without a filter, the air ventilation system must be turned off while cleaning the air filter. If you don't follow all of these steps, your filter may get dirty again faster than expected. The average reusable filter requires cleaning around once a month. Different filters have different levels of efficiency, which will determine the size and amount of dirt and debris that can prevent them from entering the system.
You can talk to your air filter supplier about the MERV ratings of the filters you use. In general, you should replace a fiberglass air filter about once every 30 days, or as recommended by the manufacturer. A pleated air filter should be replaced approximately once every three to six months. However, the frequency of air filter replacement depends on several important factors, such as your home, occupants, and location.
Keep in mind that a higher rating doesn't necessarily mean that the air filter is the right choice for your home. In addition to keeping the air conditioning system free of contaminants, oven filters also help clean the indoor air you breathe. You may not have realized that the boiler filter needs to be changed because not all air conditioning systems need heating, ventilation and air conditioning filters. A clean air filter will also lower your energy bill, as it will reduce the electrical load on your system. In most cases, air filters with a MERV rating equal to or lower than 16 are designed for residential, commercial, and institutional air conditioning systems. Clean air filters in a boiler help keep the house clean and block particles or bacteria that can damage the lungs.
However, if your heating, ventilation, and air conditioning system has a single filtration system that uses an air filter for the air conditioning unit and oven, replacements will be less common in winter than in summer. If you have a pet, Service Experts Heating & Air Conditioning of Texas recommends changing filters from 1 to 3 inches every two months. When an air filter has been in use for an extended period, it begins to gradually restrict the flow of air through the heating and cooling system. Air filters with a MERV index ranging from 17 to 20 are designed for areas that require absolute sterility, such as operating rooms or rooms for immunosuppressed people. By filtering out these contaminants, an oven filter improves air quality in the home and makes breathing easier. Also note that thicker oven filters tend to last longer, providing greater filtration over time, so they usually cost more than 1 or 2 oven filters. In general, if you find that you need to vacuum or sweep more often than usual, you'll probably need to change your air filter more often as well.
The oven filter is used to clean the air of contaminants and dust just before air enters the oven system. Air filters are designed to allow air to flow freely through them while trapping dust, dirt, bacteria, and other contaminants.
