Your selection of purifiers will be determined by what you want to get from the air purifier. If you need one primarily for getting rid of allergens and harmful particulates from the air, then a HEPA air purifier is your best bet.
A HEPA purifier uses a HEPA air filter for purification of indoor air. These air filters trap all the allergens and particulates that pass through the Hepa filter and do not let them back into the air. It is essential to note that itcan only clean and purify the air that actually passes through the air filter. If the air stays around the air purifier, but does not actually pass through it, the HEPA filters would not be able to purify such air. Thus, when choosing a HEPA air cleaner, it is essential that you choose one that has enhanced air flow capacity.
Air filters are the main part of any Hepa purifiers. These filters are usually made from very fine filtration materials, such as polymers, fiber etc. The filtration material is typically folded in pleats, tightly together, much like an accordion. These folds help to create a very large surface area of filtration material, through which large quantities of air can pass and be purified effectively.
If you remove all the pleats in a HEPA filter, you can get filtration material that is as large as 40 feet in length. The more the filtration material used in the filters, the better will be the purification efficiency of the air purifier.
Benefits Of HEPA Air Purifiers
- They typically have an efficiency rate of 99.97% in removing harmful particulates from the air.
- HEPA air filters can trap all kinds of particulates, such as pollen, dust, smoke, smog, pet dander, dead skin, mold spores etc, that are as small as 0.3 microns in size.
- HEPA purifiers can usually clean the air in any given room, up to 15 times per hour. This results in highly pure and clean air, which is absolutely fit for breathing.
- With proper maintenance and care, HEPA air filters can last you for as many as 5 years, without needing to be replaced.
- Hepa air purifiers remove all allergens and dust mites, which are especially responsible for asthma and allergic reactions in most people. Thus, using a HEPA air purifier will result in cleaner air and a healthier you.
How An Electrostatic Air Filter Works
Air which passes through the filter produces friction which causes static charges between the hairs of the fibers within the filter. This static charge attracts particles in the air which is passing through and captures it within the metal plates of the electrostatic air filter.
With this, once these filters are cleaned with water through a water hose once in a while, they can then be used again. As they don’t suffer much wear and tear, these electrostatic air filters are also given a lifetime warranty by their producers. Apart from that, the external construction is made from non-corrosive material which will not degrade due to heat from prolonged usage.
Additionally, electrostatic air purifiers are also very cost efficient as they do not require much energy to operate. Therefore, using these electrostatic filters will not hike up your electricity bills. These filters also come in many sizes and shapes, are easy to install and are also environmentally safe as they do not emit ozone into the air for cleaning purposes. Finally, with an electrostatic purifier, you will be sure that your home will be free from any pollutants which may cause allergic reactions to those within your home. Therefore, with an electro static air filter, everyone in your home will be able to breathe easier and feel fresher as well.
Features To Help With Relieving Allergies
With this, when shopping for an air purifier for allergy relief, it is important to get one that comes with a HEPA air purifier filter. This is as HEPA filters have gone through stringent international testing standards through the Department of Environment’s filter test program, and therefore maintain certain quality standards in filtering out particles. In fact, HEPA air purifier filters can filter out to 99.97% of particles up to 0.3 micron in size. This will definitely get rid of mold, dust, pollen and pet dander which are common causes of allergies.
However, some higher priced air purifiers for allergy relief are equipped with up to five layers of different types of filters to provide ultimate allergy relief. Some of these allergy relief air purifiers include UV lamps that emit UVA and UVB rays in order to kill harmful pathogenic bacteria and viruses. Apart from that, carbon filters also make up part of the air purifier in order to eliminate odors, chemicals as well as tobacco smoke.
Finally, there is a wide range of allergy relief air purifiers available in the market, starting from a few hundred dollars up to the thousands. This is because different locations, such as hospitals and factories, require different levels of allergy relief due to the difference in allergen densities in the air.
That’s where air purifier filters come into the picture. In fact, air purifier filters are economical and effective to help sieve out hazardous particles in the air. Also, many air purifiers in the market use HEPA (High Efficiency Particulate) air purifier filters which have been tested by the Department of Environment. Also, international standards are applied to these filters and test programs and procedures ensure that the quality of the filters are never compromised.
These filters act to remove 99.97% of air particles which contaminate the air, and therefore only clean air will fill your room after filtration. However, the HEPA air purifier filters, although very effective, have to be changed regularly in order to maintain its quality. On the other hand, if the air purifier has an electrostatic clean system with charged plates, the cost of replacing the HEPA air purifier filter can then be reduced.
There are many ways in which an air purifier system works to clean the air. The absorption method removes the larger particles of smoke from tobacco and odors but cannot filter finer particles. However, another method which utilizes a HEPA air purifier filter as a fine screen has the ability to filter out particles as small as 0.3 microns. As the purifier filter does not filter out chemicals, it therefore has to be combined with other types of filtration methods, such a hybrid filter which consists of electric charged plates as well as a HEPA air purifier filter.
