The most efficient way to filter household air is through the house's forced air heating or central air conditioning system. The filters are integrated into it, making a central air filtration system perfect for cleaning the air throughout the house. There are several options to choose from, such as oven filters, inlet UV systems, or whole house HEPA filter systems. It's important to note that there is a lot of misinformation about “whole-house air purifiers”.
Some air purifiers are marketed as such, but they are actually large portable units. While they can filter relatively more air, larger portable filters don't actually clean all the air in the house. The HVAC system is the only way to incorporate a true air purifier for the whole house. It could be as simple as a filter through which the return of air enters the oven (which is primarily intended to protect the oven components from dirt, rather than purifying the air), or it could be an electronic system integrated into the duct network.
For an air purifier to truly be considered a whole-house system, it must be placed in the airflow of the ducts of your HVAC system. When it comes to cleaning the air in an individual room in the house, a portable air purifier is sufficient. Some air filters are hybrids that combine both methods, and some include activated carbon elements to combat odor. Choosing the best whole-home air purifier system depends on your willingness and ability to perform the necessary maintenance, as well as the specific contaminants you want to remove from the air.
HEPA air purifiers pass air through a mesh to trap 99.97% of airborne particles and irritants, such as dust, pollen, smoke, bacteria and some viruses. An air purifier can make your home smell better as long as it has the right filters and sufficient airflow. If you don't want to take care of a facility or are looking to improve dust, allergens, pollen, pet dander, mold, or the elimination of indoor air pollution, such as smoke or odors, then a high-performance room air purifier is your best choice. The 3- and 5-ton versions of the Perfect 16 only differ in the amount of air they can filter per minute. Remember that, although a complete household unit may be cheaper, its filtration capabilities may be limited by other external circumstances, such as the size of the ducts, whether or not the oven fan is turned on all the time (it can only filter the air that passes through it) and cleaning the oven also works ducts.
A challenge with this type of central air purifier is that you only get clean air when the HVAC system is operating. A return air system is installed where air from the house is returned to the oven, before it is heated or cooled. If your home doesn't have air conditioning or central heating, portable air filters are the most practical option. In conclusion, if you're looking for an efficient way to filter household air throughout your entire home then a central filtration system is your best bet. It's important to consider all factors when choosing an appropriate system for your home - from maintenance requirements and specific contaminants you want to remove from your home's atmosphere to whether or not you have an HVAC system installed.
