The filter: Protecting your furnace
The main function of the furnace filter is protection, not filtration. Without a suited, clean furnace filter, dust and debris is allowed to flow through the furnace blower and components, coating them with gunk. A furnace is not designed to operate in such harsh conditions so it will overheat and break down. Prolonged periods of running time without a filter or a plugged filter can result in costly repairs and damage to your furnace. Today’s high efficiency furnaces are especially sensitive to disruptions in airflow and excessive dust.
We have the expertise and a variety of filters for your filtration needs. Four Seasons is dedicated in working closely with wholesalers and manufacturers to offer the most reliable furnace filters with the best performance. Check out our filter model offerings from Camfil, Honeywell, General Aire, Dust Free, and Trane in each of the filtration categories.
The filter: Protecting the air your breathe
Most homeowners are unaware, but the air inside your home can be up to five times more polluted than the air outside. While today’s better-insulated homes do a great job of keeping out the elements, they also hold in airborne particles that can aggravate asthma, allergies, and general respiratory health. Most homes generate around 40 pounds of dust every year for every 1500 square feet of space. Dust that remains trapped inside.
Clean air is a wise investment when you consider the high cost of pollution-related illnesses. Dust, pollens, mold spores, pet dander, carpet lint, and dust mite feces are just some of the pollutants we inhale. Children, seniors, and those with respiratory ailments benefit the most from fewer indoor pollutants. Today you can equip your home with new and improved filtration methods so you can feel healthy and happy with the air you breathe.
Furnace filter ratings explained
For HVAC filtration, the two most widely used rating systems you will see are MERV (Minimum Efficiency Reporting Value), and CADR (Clean Air Delivery Rate).
The Minimum Efficiency Reporting Value (MERV) is a universal standard used to compare one furnace filter’s efficiency to another’s. The MERV reports a filter’s success in capturing larger particles between 3 and 10 microns. The higher the MERV rating, the more effective the filter.
The Clean Air Delivery Rate (CADR) measures not only the efficiency with which particles are removed from filtered air, but also the rate at which clean air is delivered to your living space. Ratings reflect cubic feet per minute of clean air delivered for an average size HVAC system: the higher the value, the more effective the air cleaner. Use this rating only when considering an electronic air cleaner.
