All air purifiers are not created equal

Are you ready to take a step toward a healthier lifestyle? Maybe it's time for you to consider how your indoor air affects your health. Statistics show that more than 50% of Americans are unaware that poor indoor air quality is one of the top five most urgent environmental risks for public health. If you are thinking of buying an air purifier to solve your air quality problems (that it is smoke, allergy or even radon) ), beware of products that may have more marketing power than the actual cleaning power. Find an air filter that works for you, you must first know what pollutants are in your air. There are obvious internal offenders such as dust, dust mites and dander – but what about fumes from cleaning products or the effects of airborne bacteria? These common, but generally overlooked, air contaminants have as much of an impact on your health as airborne allergens – and they often contribute to allergic reactions and asthma attacks. Consider the short list of contaminants below to find out more about what can flow in the air in your home:


These are the germs, viruses, bacteria and mold spores that can cause the disease or an infection in people with allergies or asthma because their immune system is constantly spending on allergens. Yet even a perfectly healthy individual is vulnerable to viruses like the flu and strep – by using the correct air purifier, they can be eliminated from the air.


Odors can affect your general well-being – many people experience headaches due to certain smells of smoking, cooking, pets, etc.

Chemical Gases and Vapors

Also known as "volatile organic compounds" (VOCs) found in daily cleaners, aerosols, car/">cigarette smoke, adhesives used to make furniture and cabinets, nail products, etc.


Allergens are usually pretty big, but are still small enough to match thousands over the period at the end of this sentence. Another common source of particles is the visible smoke cloud of cigarettes, cigars and pipes.

Here is a list of methods used by different air purifiers to remove contaminants – by understanding how each air purifier works, be able to target you air quality problem:

HEPA Air Filters

High efficiency particulate filters remove at least 99.97% of 0.3 micrometer diameter particles. The filters consist of sporadically placed fibers that collect particles in the air that passes through them. Air purifiers equipped with HEPA filters will have the filter replaced when it is full. This type of air filter is very effective for people with allergies and asthma (and is approved by the American Academy of Allergy Asthma and Immunology) and are safe for people suffering from pulmonary function disorders. The HEPA is also able to eliminate visible smoke clouds from the air, even if it does not address fumes or odors (usually, the HEPA does part of a two-step technology to eliminate smoke).

Ozone is a reactive oxidant capable of neutralizing different chemicals and bacteria in the air and is very effective at removing odors. These machines use ozone to clean the air. It is not generally recommended to buy these units because of the risk of ozone buildup in a room. If you have one of these machines, it is advisable to keep these machines at their lowest level because too much ozone can irritate the delicate lungs. If necessary, you can mount an ozonizer air purifier to eliminate lingering odors while people are out of the house. These machines are best avoided by asthmatics, COPD or any other disease that affects the lungs.

Carbon-Based Air Purifiers

Due to the porous nature of carbon, it is one of the most efficient. methods of capturing fumes and chemicals. Impurities pass through the pores of carbon, where they are adsorbed and bind with carbon. Most carbon filters, like Dynamic, will also have a HEPA filter, giving a complete and highly efficient air purification system. At some point, the carbon will have adsorbed enough to become saturated and needs to be replaced. Depending on the amount of carbon used, the life of the filter varies. Dynamic air filters usually need to be replaced every three months on average. When they are used to remove smoke from an office or other room, it is recommended to change them every 1-2 months, depending on the amount of contaminants produced. (Dynamic filters also use the ionization described below to give maximum results.)


These filters have no fabric filter but create a positive or negative charge for "ionize" contaminants in the air so that they are attracted to the collection networks. This charge also causes individual particles to hook to each other, forming larger particles that are easily captured during a second pass through the machine if they were too small to collect on the first one. . Some ionizers do not have collection plates, but create a charge so that the smaller particles attach themselves until they are big enough to fall completely out of the way. air (but pay attention to these units, sometimes they only collect particles clothing, furniture, etc.)

Ultraviolet Light

Ultraviolet (UV) light sterilizes the air by eliminating microorganisms such as bacteria, viruses, germs and molds. After passing through this type of filter and being exposed to UV light, these microbes can not reproduce or grow. It is important to use the right amount of UV and that each contaminant has a sufficient duration of UV exposure (a fan that pushes the air quickly will not be the most effective way to sterilize l & # 39; air). Also, keep in mind that you need to make sure that the power of the UV purifier is appropriate to the size of the area you need for – a byproduct of UV is traces of ozone. While with HEPA filters, more power is completely safe and effective; you do not want to oversize your UV purifier – just buy the suggested power for your square feet.

Hydroxyl radicals

These cleaning agents naturally present in the earth's atmosphere are able to very effectively neutralize molds, bacteria and viruses. When the oxygen atoms draw a hydrogen atom from the water vapor, this radical is produced. Hydroxyl radicals are 1,000,000 times more powerful at destroying air pollutants than ozone. When it is used with ionizers or ultraviolet, this air purifier only retains particles, but if it is used with a HEPA filter, this is no longer a problem. Biozone makes several different models of air purifiers using this technology

What is the suggested air purifier for your home or office?

For allergies to dust, dust mites, animal dander, and pollen:

You will need a filter such as a HEPA filter to remove aggressive particles from it. ;air. By using ozonators or ionizers alone, allergens will not be eliminated, and ozone can irritate the delicate lungs of asthmatics. Examples of brands: Dynamic, AllerAir, BlueAir, etc. – HEPA and carbon

For the removal of smoke:

You will need a two-step approach to solve this problem because smoke consists of two forms of air pollutants – particles ( visible smoke) and gas (airborne chemicals and odors). A HEPA or carbon filter will remove airborne particles – but to eliminate the heavy odor, you can also use a hydroxyl radical cleanser or an appropriately sized UV air purifier. For example: dynamic, pollution search, biozone or oasis air ducts, etc. – HEPA and carbon / UV

For mold, musty odors and mold allergies:

An air purifier with hydroxyl radical will neutralize odors and sterilize spores. If the spores are no longer active, they can not germinate in a new mold or irritate the lungs. Over a short period of time, these air purifiers will help eliminate mold in your home. For example: Air Oasis, Biozone, etc. – Radical UV or Hydroxl

For asthma or other pulmonary conditions (in children and adults):

Has HEPA, carbon or even an ionizing air filter will give the best results without additional irritation of the lungs. For example: Dynamic, AllerAir, BlueAir, etc. – HEPA and carbon and / or ionization

Before finishing reading: do not forget to clean the air filter "cure-all" which promises to do everything except bend your socks! Most of the time, they will not work just because they will not have enough power for the amount of space that you need to clean up. Determine how many square feet need an air purification and ask a professional indoor air quality a recommendation based on your measurements.
