Hepa Air Purifier Reviews – With Helpful Tips and FAQ


Hello and welcome to this review on Hepa Air Purifiers which are easily ordered online and delivered to your front door hassle free. People often built homes which sealed firmly for energy efficiency as energy efficient residences are excellent for saving your electricity bill, although terrible for allergies. Contaminants as tobacco smoke, pollen, mold, dust, and animal dander can cause asthma and allergies, making house horrible and harmful for allergy and asthma victims.

HEPA (high-efficiency particulate air) filters used in indoor air purifiers can facilitate allergy patients to improve overall health. The term HEPA is came from the manufacturers, and most users can't identify the difference between a standard HEPA filter, E12 HEPA removes up to 99.5% contaminants and a medical/industrial filter. The European Norm, EN 1822:2009 specification is referred to as an initial rating for HEPA filter class, indicating total particulate retention from 85% E10 to 99.999995% U17. HEPA Filters set the high standard for air purification processes. By definition, a HEPA filter eliminate as a minimum 99.97% of all particles as small as 0.3 microns. This United States HEPA standard was initially developed by the Atomic Energy Commission to capture radioactive dust particles. HEPA filters permit simply very tiny particles to pass through them.

Allergens such as pollen, animal dander, mold spores, and dust caught trapped in the filter. The major drawback of the HEPA air purifier is that you have to change the filter at regular intervals. The most important benefit: if it is HEPA certified, subsequently you know it works well for all general particle allergens, though not all HEPA filters as size matters, as more area of HEPA filter, the extra particulate it will be able to eradicate. The size, material, and construction of filter media all play a key role in the air purifier's performance and the main reason as HEPA filter is expensive than other filters.

Tips to consider before you buy…

If you have decided to buy a HEPA air purifier for your home, its strongly recommended to go though the following useful tips:

  • Similar to other industries, there are good & bad guys. Earlier, there were problems within air purification industry. According to the EPA and consumer reports, several manufacturers were wrongly marketing, ozone cleaners were as air cleaners. Obviously, this was and is fake. Resellers and dealers come with what information is given to them and at the time a little information out about how this type of appliance could harmfully affect health. Even after additional information came to light, many continued to producers and electrostatic precipitators are hardly ever seen for housing use.
  • Make sure the area mentioned for the air purifier is about the same or slightly greater than the square footage of the room where you are going to use it. Coverage area is calculated based on an 8' ceiling, CFM, and a stated number of air exchanges per hour.
  • HEPA air purifiers range from reasonably priced air purifiers for little spaces to fully loaded air purifiers for big rooms. Primary cost isn't the only expenditure related to operating an air purifier; consider also how much replacement filters will cost yearly. For some energy usage is also a concern, although generally use little energy, some are Energy Star rated.
    If your air purifier unit contained both a HEPA filter and a carbon filter, they require to be replaced individually and after different periods of time. Regular filter replacement is very important to getting to the most of your air purifier while minimizing wear on the motor. Furthermore, several manufacturers need regular filter replacement as a condition of their warranty.
  • Some air purifiers extremely quiet although nearly all can be noisy when functioning at full power. For models with wide carbon filters, a slower fan speed can in fact produce better filtration results. It can be a bit of a balancing act when it comes to sound, but in general, there are proper fan settings with comfortable noise levels on all air purifiers. If possible, ask for a display before you buy your air purifier unit.
  • Pay mind to where you will place a new HEPA air purifier in your house. Placing a new device too close to a wall, or furniture, can slow down its filtration abilities.
  • Always read manufacturer manuals, and as a good rule of thumb never place an air purifier closer than 12″ from any surface.

Frequently Asked Questions about Hepa Air Purifiers:

Q: How do HEPA air purifiers perform?
A: Naturally, polluted air is drawn into an air purifier, in HEPA air purifiers, a washable pre-filter traps bigger and visible particles. Air then generally passes through a HEPA filter. HEPA filter media is composed of millions on very thin fibre-glass fibres that combine to form a fabric like paper. As air passes through it, allergens such as pollen, animal dander, mould spores, and dust get trapped in the tiny filaments of the filter. Many HEPA air purifiers also contain a carbon filter to capture chemicals, odours, and gases. Once the dirty air has pass through all the filtration stages, then it sends clean air back into the room.
Q: What is a micron?
A: Air purifiers are intended to reduce impurities in the air, even those impurities which are so tiny that they are undetectable to the naked eye. Microns are the common measurement expression used for these minute airborne particles. One micron is 1/25,000 of an inch. To provide you a thought of how small this is, dust mites average around 200-300 microns, and a grain of sand can be over 800 microns.
Q: What are the benefits and side effects of Hepa Air Purifiers?
A: By installing Hepa air purifiers you will get these benefits of breathing less contaminated air, keeping your allergen load below its reactionary threshold, sleeping and breathing better, and living healthier without additional pharmaceuticals or a radical lifestyle change. However little side effects of having an air purifier are as energy expenditure (average cost as 60w light bulb) with white noise. In fact, generally people naively get benefit from the white noise of air purifiers as white noise drowns out distracting background noises that can interrupt sleep, but for a lot of people, white noise can actually be peaceful.
Q: What is ACH?
A: Air Changes Per Hour number is recognized as the ACH rating, which describes that how frequently the air purifier can exchange all the air in a provided room. For instance, if the air purifier has a ACH rating of 6 for a 20' x 20' space, then it is capable of exchanging all of the air in that room 6 times in an hour. If you have allergies or asthma, you should have an ACH rating of at least 4 and preferably 6 or 8.
Q: What is an impregnated carbon filter?
A: Impregnated carbon filters have an additional chemical called "chemisorbent" which remove certain chemicals like VOCs, as oxidizing agents like potassium permanganate, potassium iodide, and potassium hydroxide. The adding of broadens the filtration variety, allowing carbon filters to eliminate a wider variety of chemical vapors and pollutants by either trapping them or oxidizing them, breaking them down into minor, inert components like water vapor and carbon dioxide.

In summary, Appliances without air quality sensors and automatic modes should be carefully evaluated before buying. As indoor air pollution increases from cleaning products, cooking, vacuuming, and outdoor contaminant infiltration, an automatic air purifier will adjust its performance as needed. Allergic reactions can be produced by a number of air pollutants varying from dust, pollen, mold spores, and smoke particles to volatile organic compounds, dust mite feces, and even off gas generated by fireplaces and automobiles. Even short-term exposure to contaminates can cause health issues, and some medical studies suggest that long-term exposure to polluted indoor air could eventually lead to severe health problems such as respiratory distress, asthma, some forms of cancer, and even death in rare cases.

Regularly using an indoor HEPA air purifier can mitigate health risks associated with home air pollutants – and even completely remove risks if used in conjunction with other air and surface cleaning techniques (this would include using a HEPA vacuum cleaner, regularly washing linens, and ensuring cleaning products are environmentally safe). Don’t let yourself be fooled by HEPA marketing hype. Some manufacturers like to tout about HEPA ratings and mention “99%,” but 99% isn’t enough data to understand the nature of the filter used for purification. Chances are, if manufacturer states 99% instead of 99.97%, they’re offering a standard HEPA filter instead of a cut above the rest.
