Air purifiers are systems that are used to clean pollutants from indoor air. Originally, purifiers were called air cleaners, as they both perform the same task of cleaning the air. In some cases, air purifiers are still referred to as air cleaners. There are various types of purifiers on the market, including air purifiers for allergies. This type of purifier is designed to not just clean the air, but to specifically remove allergens from the air. Not all air cleaners are the same, however. When an allergy sufferer is in the market for an air cleaner, it is important to recognize the differences in the purifiers that are available. This will assist him or her in picking the best air purifier for allergies.
It is necessary to take a few things into consideration when choosing an air purifier for allergies. One of the points to consider is the room's size. When a person is selecting a purifier to help eliminate his or her allergies, they will need to know what maximum size room a specific unit will filter and how many times it will do so within a certain period of time. Understanding the different types of purifiers will also help when it comes to choosing the right air purifier for allergies that the resident suffers from.
Understanding what is causing the allergies is also helpful when it comes to selecting the best air purifiers for allergies. Allergies can come from tiny shed skin cells from pets living in the home, which is called pet dander. The cigar or cigarette smoke from someone living in or visiting the house can be a source of allergies. Dust and dust mites are also common causes of allergic reactions, as are molds that may be in the house. Even pollen from outdoors can make its way into a home and act as an irritant.
Some of the best air purifiers for allergies use High Efficiency Particle Arresting HEPA filters. These are a type of fine filter that catches just over 99 percent of particles in the air. In addition, it also catches particles that are as small as 0.3 microns. This makes the HEPA filter adept at removing some of the most common allergens that affect allergy sufferers, such as pet dander, dust or mold spores. They clean the air when the purifiers fan pulls air into the unit, causing it to pass through the filter. Of the various types of air purifiers for allergies that are on the market, those that use HEPA filtration are the most effective.
When buying the best air purifier for allergies, a person may also want to consider a fabric, pleated air filter. These types of air purifiers use a different type of filter but they work much the same as HEPA air purifiers. Like HEPA air purifiers the fan pulls particles into the unit where they are captured by the filter. Unlike the purifiers that use HEPA filtration, they do not capture as many allergens and they do not capture particles that are as small. Often purifiers that are designed for the whole house will use filters. Both pleated fabric filters and HEPA filters are referred to as mechanical filtration, or mechanical air filters.
Another type of air purifier for allergies is the electrostatic air purifier. This type of purifier is an electronic air cleaner that works by charging particles with an electrical charge as they are pulled into the unit. This charge traps the particles on plates in the unit that are called collectors. Although it is not as effective as a HEPA air purifier for removing certain allergens, it is still one of the best air purifiers for allergies, such as pet allergens, pollen, and smoke. In addition, they are also typically inexpensive to operate.
While purifiers are an effective way of reducing allergens, even the best air purifier for allergies cannot eliminate all allergens on its own. To help make the air cleaner, a person can take certain steps in addition to using an air purifier. This involves eliminating the source of the allergens and keeping the home well ventilated. To do this a person will want to regularly perform certain tasks, such as opening windows as frequently as possible, vacuuming and dusting on a regular basis to remove dust and dust mites, and adhering to a strict policy of no smoking in the house or apartment. When these steps are combined with effective air purifiers for allergies, they can make a significant difference for the allergy sufferers who live in the home.
