One of the top health concerns includes indoor air pollutants. Using a whole house air purifier is one way to address the issue of indoor air pollutants. These purifiers work by controlling or eliminating the source of the pollutants. The purifiers are attached to the existing central heating and/or air system and work by filtering the air as it passes back into the house. But is this type of purifier worth investing in?
There are five types of air purifiers that cover the entire house. There is the High Efficiency Particulate Accumulation or HEPA for short. It removes 99.97% of particles from the air and requires and strong blower. It uses woven glass particles and these particles are formed into a filter that has a very large surface area. The second type of purifier is the electronic purifier. It removes 95% of dust and about 85% of microscopic particles. It works by drawing particles inward by fan and then charges them with a high voltage wire. Another charge then attracts the particle as they pass. The third type if purifier is the self-charging electrostatic purifier. This type of purifier blocks about 10% – 35% of particles in the air. It works by using synthetic fibers that create static charge to attract particles. The fourth type of purifier is the ultra-violet light purifier. There is no method used to determine it rate of removal although 室內空氣污染物檢測 most units in this class have limited effectiveness of killing bacteria and mold. This purifier works by sterilizing air that passes UV lamps via blowing air. The fifth type of purifier is the ozone-ionizer. It works in two steps to clean the air. The ozone (naturally occurring gas) purifies the air by oxidation. The ozone then penetrates into the molecules of the pollutant. The second step is ionization. The particle in the air is charged with negative ions and these charges attach to the particles forcing them to drop out of the air.
Now that you know how the air purifiers work, let’s take a look at some of the reasons you may want to invest in one. When the air purifiers are attached to your central heating and/or air system, it significantly reduces the amount of noise than a room air purifier. If you live in an area with a lot of outdoor pollutants or have someone in your home with asthma, these types of purifiers are a great investment. Many people take their central heating and/or cooling system for granted and never really thing about them at all. When a full house air purifier is attached, it requires much attention especially when the filter needs changing.
There are cons to consider when purchasing purifiers that cover the entire house. These types of air cleaners will require a qualified technician for installation. After they are installed you have to thing about the filters. Sometimes the costs of the filters can be greater that a room purifier. If these purifiers break down you have to call a technician and that can be costly also. Another thing to consider is air from a central heating and/or cooling system does not flow equally through all rooms so there can be a buildup of dust and other allergens in some areas of your home. Because the air purifiers only work when the heating or cooling system is continuously running, you may incur a rather expensive electric bill. Also consider the regular replacement of the filters, which can be very expensive also. And remember the ozone-ionizers drops particles out of the air and they can land anywhere in the home.
There are only a few options to consider when investing in a whole house air purifier. There are health issues, cost, and the type of purifier to buy. Also check the technical specifications to make sure that it can benefit the square footage of your home. You may also want to see about do it yourself maintenance like replacing air filters. And remember all purifiers work differently. So consider some of these pros and cons when considering if a full house air purifier is right for you.
