Buyer's Guide for HEPA Air Purifiers
First of all, the primary function of the air purifier is to clean the air in a room. For the purification to occur, air in the room has to go through filters that capture pollutants in the air. Meanwhile, fans force the air through purifiers. Now, there are two ways these fans can work. The first is by manually turning the fans on or off. While the alternate way is for the air purifier to monitor pollutant level in the air and automatically turn the fans on or off depending on the pollutant level. In fact, this auto mode is a far more convenient and energy efficient way to operate the air purifier.
Does Size of the Room Matter?
In fact, the size of the room does matter. By the way, each HEPA air purifier specifies the optimum square footage of the room the air purifier is designed for. For example, a small room is usually around 200 to 300 square feet. Meanwhile, master bedrooms or living rooms can be anywhere from 400 to 800 square feet. So, one of the first things to do is measure the square footage of the room where you want purified air.
Now, filters help remove pollutants from the air. So, the more the better. But, not always. For example, if you don't have pets in the home, there is no need to have a filter that helps remove pet dander, hair, and odor.
A warranty helps with peace of mind once you’ve invested.
Frequently Asked Questions (FAQ)
What are HEPA Filters?
High Efficiency Particulate Air or HEPA filters are the most basic type of air filters. These filters filter air as it flows through the machine by trapping particles too big to go through the filters. Now, True HEPA filters are certified to capture 99.97% of particles larger than 0.3 microns. By the way, mold spores can range from 1 to 100 microns.
Because HEPA filters are the most basic type of air filters, they are also the most reliable. However, you have to ensure that the filter remains clean. And, one of the ways to do this is to replace the filter at least once a year if not more often.
What is a Carbon Filter?
First, a carbon filter is made of activated carbon, also called activated charcoal. In fact, carbon air filters help trap odors through a process called adsorption. In this process, molecules attach to the outside of a surface, rather than being soaked into it. So, the more porous the activated carbon, the better, as this will increase the amount of surface area available for contaminants to latch onto when air passes through the filter. Therefore, carbon filters remove odors caused by pets, cooking and mildew, Consequently, these filters are great in homes with smokers or pets.
What is CADR?
First and foremost, CADR or Clean Air Delivery Rate is measured in cubic feet per minute or cfm. Now, CADR was developed to measure the performance of residential air purifiers. Also, the Association of Home Appliance Manufacturers (AHAM) oversees the CADR rating program.
Most of all, the CADR rating reflects the volume of air in cubic feet per minute that is cleaned of particles of certain sizes. So, to measure the effectiveness in removing particles of different sizes, three types of particles are tested: smoke, pollen and dust. By the way, these represent small, medium and large sized particles respectively. Therefore, each particle is measured and assigned it’s own CADR score.
So what do you get out of a CADR? Well, the CADR rating gives you a way to compare air purifiers that consider both air flow and filter efficiency. In fact, the CADR is basically a reflection of the air flow (in cubic feet per minute or CFM) times the efficiency of the air filter. Therefore, if an air filter has a capacity of 200 cfm and 100% efficient the CADR would be 200. On the other hand, if the air filter has a capacity of 200 cfm but only 50% efficient the CADR would be 100.
What is UV-C Light?
Ultraviolet Germicidal Irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
By the way, human overexposure causes temporary skin redness and harsh eye irritation, but no permanent damage, skin cancer, or cataracts.
What are Volatile Organic Compounds?
Volatile Organic Compounds or VOCs are emitted by a wide array of products. For example paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbon less copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions.
Also, organic chemicals are widely used as ingredients in household products. For example, paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. In addition, fuels are made up of organic chemicals. Now, all these products can release organic compounds while you are using them, and, to some degree, when they are stored.
What is CARB Compliance?
All portable indoor air cleaning devices sold in California must be certified by the California Air Resources Board (CARB). To be certified, air cleaners must be tested for electrical safety and ozone emissions, and meet an ozone emission concentration limit of 0.050 parts per million. In fact, there is an official list of air cleaners that are CARB compliant.
