Air Purifiers

Life is good for the air purifiers industry. With research indicating that the soaring rates of respiratory ailments are the result of higher levels of household air pollution found in American homes, residential air cleaning methods have been selling as hotcakes.

But take a moment before you sign up for the horde of people rushing out to a huge box retailer for the latest in air scrubbing technology. Finding a quality air cleaner is tricky, along with a bad one might pollute your air more than clean it. But with a little preparation, you are able to up the chances of yours of finding a system that’ll perform the job. Here are some actions homeowners should take prior to purchasing a home air cleaner.

  1. Determine Your Needs

Many kinds of air purifiers fill up the market place, and they perform in ways which are different and also target various pollutants. Finding one that suits your needs calls for you’ve a clear knowledge of what those requirements are. A person struggling with mild allergies has a very different group of needs from someone with severe asthma or autoimmune deficiencies. Clarifying your needs can allow you to avoid wasting money on a system that does too little or too much. Furthermore, upon reflection, most of you might see that you do not really need a purifier whatsoever.

  1. Stopping Indoor Air Pollution at the Source of its

You would not deal with a mosquito issue by lighting citronella candles while a plastic kiddie swimming pool filled with fetid water sits in the backyard of yours. Similarly when dealing with air quality, it is a good idea to address a problem at its point of beginnings.

Pollutants come from a range of sources within a typical residence and preventing their occurrence requires a detailed multi-step approach including:

Cleaning – Vacuuming floor coverings, dusting home furniture, addressing mold and mildew build-up, as well as cleaning out your HVAC systems air ducts.

Dehumidification – Installing a dehumidifier to address high moisture levels that often exacerbate pollutant levels.

Maintenance – Ensuring that stoves, dryers & your HVAC system all are in working order.

Ventilation – When possible, incorporating mechanical or natural ventilation to help bring down levels of household air pollutants.

Often times, addressing these problems will fix your air quality issues and wipe out the demand for an air cleaner altogether.

  1. Decide between a space and perhaps Whole House Purifier

Probably the most significant choice you’ll make about an home air purifiers buy is whether you want a central purifier that cleans your whole home, or an area only purifier. Each type has distinct advantages:

Bedroom Purifiers

These are the ones you will find in Best Buy, Sharper Image or any other electronic stores. They are usually free standing products which do not demand professional installation and in addition they range from less than $200, to more than $thousand. Many manufacturers place them out and they can consume a range of systems to cleanse the atmosphere.

As you would expect, these systems are perfect for keeping air which is clean in a single room. When you are experiencing allergies which hinder the sleep of yours then one air purifier put into the bedroom could possibly be what you should do.

Moreover, take into account that most room purifiers are portable, and thus you are able to take them around the home and thus avoid having to buy multiple systems.

Here are a few cons and pros of room only purifiers


Often cheaper than total house alternatives

Usually do not require professional installation

Do not require a forced air HVAC system for operation



Take up space in living area

Frequently noisy

Generally don’t work also at lower (and quieter) speed settings

Occasionally create smells

Total House

These systems normally connect in your forced air HVAC system, being drained of its ducts and fans to draw air in to the cleaning unit. Majority of methods are fitted into your HVAC ducting.

The price and complexity of whole house purifiers range from cheap, do-it-yourself cleans that just replace the regular furnace filter; to pricey systems needing professional installation & costing hundreds. Some of the priciest systems are freestanding self-powered units which rely upon ducting but operate liberated from the HVAC system.


Quieter than room only systems

Doesn’t take up space in your living area

Ideally situated, as HVAC ducting is often a prime tool of air pollutants, mildew, particles etc.


Typically expensive

Critics claim that whole house systems don’t target specific rooms as well as a room air purifier

By and large need a forced air system

Usually do not work when HVAC is off four. Find out the various Methods of Purification

Air purifiers are able to use lots of tasks in their operation, many of which target certain pollutants while missing others. Others excel at removing particulates including pollen and dust but miss gaseous pollutants like carbon monoxide. Others simply target viruses or bacteria. And some do not actually target anything at all. i.e. several don’t work!

Common kinds include:

Media/HEPA Filters

These systems trap particulate matter through the usage of physical filters. The bulk of genuine purification systems incorporate some form of media purification technology. The most practical of these’re HEPA or perhaps High Efficiency Particulate Absorbing filtration systems which are very good at cleaning the air of particulate matter that they’re used in hospitals and other facilities which depend on sterile air.


Excellent at capturing particulate pollutants

Most of the top rated performing purifiers are of this type

Require very little maintenance

Typically increase in effectiveness as they are used


The greater efficient filters block airflow and hence can certainly reduce efficiency of HVAC systems

Replacing screens can be pricey

Filters that incorporate an electrostatic charge will rapidly lose efficiency

Media screens can be hotbeds for bacteria


These purifiers pump ions into the atmosphere. The ions transfer their charges to airborne particles causing them to connect to other surfaces or walls and so taking them from the air. The process may sound phony although it really does work. Sadly it also has the side effect of creating ozone, a poisonous gas which can exacerbate asthma and which also happens to be the primary component of smog.



Typically Effective

Typically, less expensive to maintain than HEPA systems. (No filters to replace)


Produces ozone Ionization results in pollutants attached to home surfaces, that may ultimately result in a blackening of those areas.

UV Lamps

These purification systems consist of UV lamps, whose job by irradiating germs with lethal doses of ultra-violet radiation. They are designed solely to kill germs however and thus should only be used in addition to a filter system.

Warning: While all UV lamps generate ozone as a bi-product of the cleaning process, a few are designed especially to generate ozone. These need to be stayed away from.


Effective in killing biological contaminants

Inexpensive and require very little maintenance


Only kill germs

May produce ozone which assists in destroying viruses and bacteria but which can prove harmful to humans

Entire house UV lamp systems require professional system as incorrect installation is able to lead to damage to eyesight

Gasoline Filters

These filters use activated other substances or carbon to hole volatile organic compounds as well as other gaseous pollutants. They may be effective when used along with a particle filter. They tend to be discovered more in industrial and commercial uses than in homes. In residences these filters are often found in combo with a HEPA style form of filtration in high-end purifiers.


The best way to filter gaseous pollutants from your air


These filters typically can only target specific types of gasses

Cheaper residential versions are usually not effective

Ozone Based Air Purifiers

The villains of the air filtration world, ozone producing air purifiers intentionally create ozone gasoline due to the ability of its to neutralize pollutants of all types such as bacteria, VOC’s as well as particulate material such as pollen and dust. It can also get rid of unwanted odors.

In residential situations however these methods are largely ineffective on account of the lower levels of ozone used, moreover they can prove damaging to residents as ozone has been linked to breathing issues. Most reputable experts and publications advise that ozone home air cleaners never be used in residences. California has gone so far as to ban them.

  1. Learn the Lingo

Manufacturers will throw lots of terminology at you when trying to hawk the contraptions of theirs; it helps you to understand just what they are speaking about. Several of the key terms include:


Effectively a millionth of a meter, the micron, or maybe micrometer (symbol m) is probably the most widespread unit of measurement employed to describe the size of particles a filter is able to catch.

In order to give you a comparison here are a few common measurements of dust in microns.

Human Hair 30 m – 120 m

Particles visible to eyes 50 m

Pollen 10 m

Respirable particle 10 m as well as under Bacteria.3 m

Viruses.003 m

Respirable Particles

Respirable particles talk about airborne matter 10 m in size or perhaps smaller. These particles are able to get deep into your lungs and cause both respiratory and cardio issues.


Standing for Clean Air Delivery Rate, the CADR system was created by the Association of Home Appliance Manufacturers (AHAM) to determine the volume of air properly treated by a portable air purifier. CADR ratings are often found on the unit’s packaging and consist of three numbers each representing the air purifiers effectiveness in catching major forms of particle pollutants: dust, pollen and smoke.

When attempting to make good sense on the amount structure, AHAM suggests you buy an air home cleaner that has a smoke rating 2/3 the square footage your room. So a 10 ft. by 15 ft. space with a square footage of 150 foot would need an unit with a CADR smoke rating with a minimum of 100. This quote assumes a ceiling level of 8 feet. A greater ceiling is going to require a better CADR rating.

Understand that while CADR is a commonly respected method, lots of purifier producers do not use it and don’t be surprised when while going shopping, you run across brands without an AHAM CADR seal.


MERV stands for Minimum Efficiency Reporting Value and was developed by the American Society of Heating, Refrigeration and Air conditioning Engineers(ASHRAE) to calculate a filter’s capacity to trap dust and other particle pollutants.

The score scale ranges from 1 16, with 4 being the rating for a normal dust filter used to protect your HVAC system as well as sixteen being a filter so effective it is able to catch about 95 % of particulate matter and is often used for surgery. True HEPA filters meanwhile aren’t supported by this machine but would rate a place between 17 and 20.

Most home owners won’t need or perhaps necessarily actually love a MERV sixteen air filtration system, as these air filters restrict airflow to the level of lowering the efficiency of the entire house HVAC system where their located or, in the situation of room only purifiers, cause them being noisy and energy consuming. Moreover, numerous filters that claim MERV sixteen ratings or above actually prove to be less successful than lower rated filter systems; which brings us to our next topic:

  1. Research All Models before Purchase

Research is crucial to picking an excellent air purifier but unlike cell phones, computers, and other buyer solutions, discovering quality research on air purifiers is difficult. Properly testing an air purifier requires proper facilities. However, a lot of these proper facilities are supposed to be to the very manufacturers who produce the systems; minimal conflict of interest.

So do thorough research. Check out credible publications, consult medical professionals and HVAC, and take advice from any trusted friends or associates using purifiers.

And for most people, do not obsess above your house’s air quality. Unless you have a serious health condition you just do not need to invest a lot of money with the intent of keeping your house 100 % pollutant free and the benefits you will acquire from the thoroughly clean air could perfectly be negated by the stress a result of the pursuit of yours.
