Honeywell Home air filters capture particles while allowing more airflow for a longer period of time. Learn More Next page How do I install an air filter? Our air filters should be placed inside the intake boot, ensuring a tight-fitting seal so that the filter works to the best of its ability, filtering out as much bacteria, dust, mold, pollen, viruses, smoke and airborne particles. What if it's too tight to load into my furnace? The air-tight seal of the filter is crucial for best performance. This filter fits MOST 16x25x4 in. boots, but unfortunately there are some boots that may not be compatible. Consult your owner’s manual for manufacturer recommended specifications. Does the arrow point up or down on an air filter? The arrow should be pointing in the direction that air flows through your system, which is typically the direction of the furnace's air handler or blower compartment. What happens if an air filter is not changed? A dirty filter reduces the airflow to your HVAC system and causes it to work harder. It uses more energy, which may cost you more money. It also might not be able to keep your home at the proper temperature. Do I use the same filter for Heat and AC? Yes. You might hear them called furnace filters or air-conditioning filters, but if you have the kind of common system where hot and cold air travel through the same ducts, the filter for the two systems is the same.

Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.75 x 15.75 x .75). All filters have both. Measuring Your Air Filters If your current air filter does not have a dimension listed on the frame, use a tape measure to record the length x width x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online. Why should I change my air filter? To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs. Will these air filters fit my system? Most of our filters are universally compatible, and will work with virtually any furnace, air conditioner, heat pump, or HVAC system. But if you see a specific brand name like Honeywell within a product title, then it is designed for an exact model. How do I change my air filter? Once you find the right size, turn off your power supply and remove the cover from your intake vent. You can then take out the old filter and dispose of it safely. Finally, just insert your new filter, replace the cover, and turn the power back on. How often should I change my air filter? We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But, this is subject to change based on filter size and variable factors for pet owners, allergy-sufferers, homes with children, etc. How many air filters do I need? This varies for every customer depending on specific needs like those referenced in the prior answer. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.

He formed the Butz Thermo-Electric Regulator Co., Minneapolis, in April, 1886, and soon invented a device he called the "damper flapper” – an ingenious predecessor to the modern thermostat. Here's how it worked. When a room cooled below a predetermined temperature, a thermostat closed the circuit and energized an armature. This pulled the stop from the motor gears, allowing a crank attached to the main motor shaft to turn one-half revolution. A chain connected to the crank opened the furnace's air damper to let in air. This made the fire burn hotter. When the temperature rose to the preset level, the thermostat signaled the motor to turn another half revolution, closing the damper and damping the fire. The temperature correction was automatic. Over the years, many Honeywell products have been based upon similar, but more complicated closed-loop systems.

text: Product Description Product Description Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size". With the 4" and 5" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. If you are replacing a 4 3/8 depth 20x25x4 filter in your Honeywell unit you should order our 20x25x5 Honeywell Replacement air filter that measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38). Nordic Pure 20x25x4 Pleated Air Filters MERV 12 are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. All Nordic Pure pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. MERV 12 furnace air filters are comparable to HVAC filters with the rating of MPR 1500-1900. This high-performance HVAC replacement filter will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance. It is important to regularly change your furnace air filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy. From the Manufacturer Nordic Pure 20x25x4 MERV 12 Pleated AC Furnace Air Filters: Actual Size: 19-1/2-Inch by 24-1/2 -Inch 3-3/4-Inch. IMPORTANT NOTE: Almost ALL filters are a fraction of an inch smaller than the nominal size printed on the filter. It is best if you measure your filter for the EXACT size and compare it to our "Actual Size" listed above. With the 4-Inch and 5-Inch filters there are many different exact sizes for the different HVAC manufacturers. Because of this, your filter may say 20x25x4 on it but really be the same as our 20x25x5. This is why we ask you to measure your filter so you aren't surprised if the filter doesn't fit! You may also want to look at our Honeywell replacement 20x25x5 filter. Just check the "Actual Size" before ordering. Changing your air filter is the first step in insuring your HVAC system runs at its optimal level this season. Generally, you should change your 4-Inch air filters every 3 to 6 months. Particles in indoor air are measured in microns, which are 1/1000 of a millimeter. A human hair is about 100 microns wide. A MERV 12 Nordic Pure air filter captures airborne particles as small as 0.3 microns! Nordic Pure air filters do not kill germs, however, the filter media does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs. Nordic Pure air filters are made out of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet. Electrostatic filters help trap airborne particles to protect your family from allergy causing pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.75 x 15.75 x .75). All filters have both. Measuring Your Air Filters If your current air filter does not have a dimension listed on the frame, use a tape measure to record the length x width x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online. Why should I change my air filter? To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs. Will these air filters fit my system? Most of our filters are universally compatible, and will work with virtually any furnace, air conditioner, heat pump, or HVAC system. But if you see a specific brand name like Honeywell within a product title, then it is designed for an exact model. How do I change my air filter? Once you find the right size, turn off your power supply and remove the cover from your intake vent. You can then take out the old filter and dispose of it safely. Finally, just insert your new filter, replace the cover, and turn the power back on. How often should I change my air filter? We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But, this is subject to change based on filter size and variable factors for pet owners, allergy-sufferers, homes with children, etc. How many air filters do I need? This varies for every customer depending on specific needs like those referenced in the prior answer. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.
