Generally every 2 - 3 months, but you may want to change them more often. During periods where you are using your HVAC system continuously, we recommend changing monthly to maintain the best indoor air quality. The following chart should assist you: quot;The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace your air filters[..

The air filters generally ship within 4 to 10 business days. If you order a Custom Size Air Filter, we generally need from 10 days to 2 weeks to manufacture your custom air filter plus delivery time. AC Filter shipping is by UPS Ground from Celina, TX or Tulsa, OK. Time in transit will vary. We cannot ship to P.O. Boxes. You will receive an email with your tracking number from UPS Quantum View when your package ships.

Virtually all apartments provide air filters for their tenants. Normally, cost is the primary consideration given to air filters for HVAC systems. As a consequence, you are not likely going to get the best air filtration possible. We recommend you contact the Property Manager and explain your desire to obtain a higher-quality filter in your HVAC system.

Nordic manufactures all of our air filters using a filter media that contains a permanent electrostatic charge causing dust to cling to the air conditioner furnace filter using the same principle as static electricity. As a consequence, our air filters are far more effective and efficient than traditional pleated filters. Nordic does not endorse or sell the permanent metal electrostatic filters.

Nordic Pure Merv 12 filters have a low air flow resistance for residential and commercial heating and cooling systems. Air flow is generally measured as a difference in air pressure on each side of the filter, measured by an instrument that uses water in a measured column to show air pressure. The higher the pressure difference, the more the water in the instrument moves. Its movement is measured in inches. The more inches of water moved, the more the pressure difference.

Nordic Pure air filters do not kill germs, however, the material our air filters are made out of 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. Odors are most often a combination of gas and particulate. Nordic Air Filters do not remove the gases but can remove the particulate.

Long before we began to look at air filters as a source for improving our indoor air, manufacturers of heating and cooling systems routinely incorporated air filters into the design of their air handling equipment to minimize the invasion of life-robbing air pollutants like dust, dirt, pollen and other airborne particulates. Little consideration was given to the quality of the air that was passing through the system and into the living area.

We strive for 100% satisfaction. We are so convinced our air filters will exceed your expectations, that if they do not, you can return the pleated air filters within the first 30 days, for a full refund. And because once you are a customer, we want to keep you as a customer! To that end, if you move or upgrade your unit, we will allow you to exchange the unused air filters for the proper size for your new HVAC system. Simply call us Toll-Free at 800-590-0339 to request a replacement.

Yes. When shopping for an air filter system, look for one that can recirculate 8 or 10 room volumes per hour. This doesn't guarantee completely clean air, but it will be much cleaner than with systems that recirculate less. You should also ask about efficiency. You need a system that removes more than 90 percent of all particles larger than 0.3 microns in diameter. Most indoor allergens are larger than this, so this efficiency standard will handle them easily.

Air conditioner furnace filters in most homes are generally located behind an air intake grate in your home’s walls, ceiling, basement or attic. These generally look like large vents, but the air flows into them, rather than out of them when the heating or cooling system is blowing air. They may also be located in or near the air conditioner or furnace. Many homes may have more than one, and they may be different sizes.

Though we touched on the subject at the beginning of the FAQ’s, you will find this is no longer a popular option as the handling of messy, used filters combined with the cleaning process turns off most people. Reusable filters must be cleaned and maintained as much as 2-3 times more frequently than disposable pleated air filters. Pay special attention to the removal of all moisture before reinserting the reusable air filter back into the HVAC system.

Fiberglass air conditioner furnace filters are designed only to capture large particles and to protect your heating and air conditioning system; they do nothing to remove smaller particles like many allergens. These types of air conditioner furnace filters also have either no Merv rating assigned to them or in some instances, have a MERV rating of from 1 to 4.

American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has established standards, which primarily uses two different methods for describing filtration efficiency Test 52.2 and Test 52.1

Home-Improvement:Interior-Design-and-Decorating] HEPA (High Efficiency Particulate Air) filters are recommended by allergists and medical professionals for the removal of all dust particles in the size range of droplet nuclei from the air. Home-Improvement:Interior-Design-and-Decorating] Many people mistakenly assume that an air conditioning only controls the temperature of a living space. Air conditioning also involves the cleanliness of the air.

Air filters, including High Efficiency Particulate Air (HEPA) filters have been used for many years in heating, ventilating, and air conditioning (HVAC) systems. Some are very effective in trapping particles like pollen and dust. Unfortunately they cannot trap minute particles like viruses, most bacteria, and mold spores that breed in the dark moist interiors of HVAC cooling coils and drain pans, which are located downstream of filters.

For optimal performance, we recommend that you change all Blueair air filters every six months. This will guarantee that your Blueair air purifier will continue to work effectively and efficiently to provide you with clean air. Join the Clean Air Club, achoo! ALLERGY's Filter Replacement Program, and you'll receive free reminders when it's time to change your filters.

Fortunately, Honeywell air purifiers contain a permanent HEPA filter which never needs replacing. Just vacuum twice a year! The Pre-filter will last an average of three months for both Honeywell Enviracaire and Quietcare air purifiers.

Filters can be autoclaved up to 20 times, each Midisart 2000 filter come with a memory disk for marking the sterilization cycles.

Always check the owners manual to determine when fluids and filters should be replaced. It is very important to note that there are different recommended change intervals depending on the type of driving you do. If your driving habits frequently include any of the above conditions, you should follow the Severe Maintenance Schedule.
