Choosing a Right Air Purifier for Your Home

Air pollution is not just confined to outdoor places. There are many sources that promote air pollution in any home including inadequate ventilation, combustion sources, building materials, furniture, household cleaning products etc. Air inside your home contains substances such as pollen, animal hair, dust, cigarette smoke and many other harmful contaminants. Prolonged intake of such air may result in conditions such as allergies and asthma. It has therefore become necessary for people to opt for an air purifier to avoid such problems.

A wide range of air purifiers are available in the market. In order to choose right one for your home, you should consider certain factors. Some of them are discussed below.

Types of air purifiers
An air purifier can remove most or all the impurities present in the indoor air. It is necessary to know about different types before choosing one.

•High-Efficiency Particulate Air (HEPA) purifiers trap air borne particles, when the air is forced through filters. They remove air pollutants of 0.03 microns or greater in size. They are efficient in removing solid dust particles, pollen, and mold spores. However, they are unable to remove bad odor and chemical fumes.

•Ionic air purifiers provide a negative charge to the particulate matter in the air, which is attracted to positively charged pollutants in the air. A combination of these particles is heavy and hence they settle down. Some of them may also contain two metal plates with positive and negative charge air sanitizer machine that attract oppositely charged particles present in the air.

•UV air purifiers sterilize the indoor air by making it pass through UV lamps using forced air. They are effective against microbes such as bacteria and viruses. They can be chosen to provide a cleaner place for a sick family member in your home.

•Ozone air purifiers are efficient to remove bacteria, chemical fumes, and bad odors. They release ozone into the air that disinfects the microbes and other particles. However, excess ozone in the air is harmful to your health. Also, combination of ozone with other substances may create new pollutants.

•Carbon purifiers incorporate adsorption technology. When the particles and odors pass through the filter, they are bonded to the activated carbon. They are suitable for adsorbing gases, odors, chemicals, and fumes.

Based on your requirement, you can choose any of the above mentioned types for your home.

Factors to consider
Right air purifier helps you get rid of different impurities in your room. Consider the following factors to choose a right one.

•Area coverage
The area covered by an air purifier is one of the important factors you need to consider. You need to ensure that the square footage for the purifier is same or greater than that of the room. It is an accurate measure for value. Their cost varies with their area coverage rate.

•Air changes per hour (ACH)
It refers to the frequency of air changed in the room. The minimum ACH for an air purifier used for residential purposes is about 4. This means that the air should be exchanged frequently for at least 4 hours. It is essential to consider ACH as a clean atmosphere in the room depends on it.

•Replacement of filters
Regular maintenance of filters in air purifiers is necessary. The filters which trap the air pollutants and dust particles have to be cleaned or replaced regularly. You need to check the costs associated with filter replacement. Some of them have a specific feature to monitor the filter replacements that reminds you to change the filter.
