A Whole House Air Purifier - The Ultimate

Sometimes The Answer Is A Whole House Air Purifier.

Central air cleaners will allow a person to clean all of the air in their house with one unit. You should only consider this type of air cleaner if you have a central heating, cooling, or both that circulate air throughout the house. The way a central air cleaner works is that it is tied in with the existing central air system in the home. The central air system will circulate the air back into the rooms of the house through the ductwork and out the supply registers and the air will return back to the system through the return ductwork. A central air cleaner is installed by having the return air drawn into the intake of the air cleaner and the cleaned air then is circulated back into the central air main return. It is recommended to intercept the air at the end of the main return just before it goes into the furnace or air conditioner. The installation consists of two openings in the main return at least 6 feet apart to prevent shortcutting. Ducting is run from the first opening to the intake of the air cleaner and then from the outflow of the air cleaner back to the second opening. The airflow of the air cleaner is only to draw the air from the main system to clean it and not to circulate the air throughout the house. It is for this reason the central air system needs to be running while the air cleaner is running. A central air cleaner is not strong enough by itself to push the air through the HVAC system and out to the rooms of the house and then back into the system. We recommend setting the HVAC system with the fan on, so the air will circulate regardless of the temperature setting.

Keep in mind, a central air cleaner will be able to filter out most of the particulates and remove most of your gases and odors but it will never be as efficient as a free standing air cleaner in a specific room exchanging the air several times an hour. While the central air cleaner will exchange the air in the house 2 to 4 times an hour because of all the registers and duct work in the home 90% and better efficiency is difficult. The big advantage is if you have a 2000 to 4000 square foot home, you will be able to clean the air with one air cleaner as oppose to several units and it will be quiet.
