What Is Hepa In An Air Purifier

Functioning

Air purifiers employ various techniques for air purification like absorbents, ionizers, mechanical filters etc. Absorbents can be in the form of activated charcoal and ionizers can be in the form of electrostatic chargers. Some air purifiers have additional systems like germ killing UV light, ionizer for neutralizing contaminants.

Allergic applications

Air purifiers are most popular for asthmatics and allergic people and they work by keeping allergens and triggers out of the air in homes. Allergens or triggers can be dust, pollen, mold spores, fungus, pet hair, smoke particles, airborne gases etc.

HEPA filters

HEPA is an acronym for High Efficiency Particulate Air. HEPA filters are very popular for air purifiers. Before being designated as HEPA, air purifiers must meet very stringent requirements as laid down by the Department of Energy. HEPA filters should remove at least 99.97 % of air borne particles of 0.3 micron size at 85 liters per minute rate. However HEPA filters are very expensive and replacing the filter in the purifier may cost as much as the purifier itself. Further HEPA filters cannot remove gases or odors from the air. For removing gases absorbent type of air purifiers are suitable.

Ozone

Some Ionic air purifiers produce ozone in the delivered air. Ozone can be dangerous at higher concentration, which is the cause of a controversy. However ionic air purifiers are associated with healthy air environments such as waterfalls, mountains etc, since these places have a negative ion concentration as in ionic air purifiers. An ionic air purifier in conjunction with an air filtration system is suited for most purposes.

What to look for

Customers usually look for aesthetic appeal, noise levels, size of the equipment, frequency of filter replacement, electricity consumption, air delivery rate etc. Most of the filters can be cleaned easily by vacuuming, by water or by hand. The filters may need replacement anywhere between months to a few years depending upon the type of air purifier.

Feeling nauseous? Do you have less energy than you used to, but can’t seem to find the reason why? The truth is, quite often our homes can be our worst enemies -- and we don’t even know it! Dirt, dust, pet dander, carpet fibers -- ever wonder where they go when you’re not vacuuming? Unfortunately, it’s doing much more than you probably think: it’s polluting your air.

Air Ozone Purifiers: Are They Good or Bad?

By Mark E. Richardson

Ozone is like the sun. Without ozone you would die. Yet too much can affect your health. So when air purifier companies try to sell you that ozone air purifiers are “death machines” or ‘healthy air miracles” the truth is somewhere in the middle.

How The Controversy Started

A year ago Consumer Reports claimed the Sharper Images Ionic Breeze air purifier emitted 150 to 300 parts per billion of ozone in samples taken 2 inches from the machine. This report led to the highly successful Ionic Breeze infomercials being pulled from TV. The Breeze image ionic Sharper Brand died, replaced by the Oreck air purifiers with overpriced infomercial units.

( Sharper Image’s Breeze Ionic Midi, breeze ionic plus professional, and breeze ionic quadra review models no longer have an Ozone problem. )

Let’s look at both the “good” and the ‘bad” about Ozone in Air Purifiers:

Ozone is Good…

• You would die if there was no ozone.
• Ozone is simply oxygen with an added molecule.
• It is nature’s own air cleaner.
• Ozone is produced by nature and cleans the air.
• At low levels, as found in nature, it does a superb job of cleaning the air.
• Some purifiers allow for on/off Ozone, allowing you to “treat” the room
• All electric motors, and computers, produce Ozone

…and Ozone is Bad

• The EPA standard for ozone exposure is 80 parts per billion over 8 hours.
• Ozone levels over 100 parts per billion can causes injury to the airways
• “High Ozone” warnings signal that the air is bad.
• High levels can irritate lung tissue
• Even air purifiers that claim “no ozone” produce ozone if they have a fan.

Conclusion: When used properly ozone is very helpful at treating odor, mildew and mold. In 1985, even though I was an asthmatic, I used an ozone purifier. It helped my sleep by treating a mold and mildew problem in my bedroom.

For Asthmatics: Many people with asthma or lung problems consider avoiding ozone. If you like ozone for ocassional rom treatment (as I do) find a unit with low levels, timed, and don’t sleep too close to it. You may also want to treat the room and leave the room empty for 3-6 hours. The ozone will fade in that time.

So Do You Want It In Your Purifier?

My advice is to find a unit that offers optional, timed ozone when you need or want it.

I now own an air purifier with optional on/off ozone that has a 2 hour ozone timer. I use it maybe 1 or 2 days a week when any room in my house gets musty smelling, and in the bathroom when it smells moldy, or mildewy . It freshens the room better than anything.

I hope I have “cleared the air” on the great ozone conspiracy.
