Air Purifier Basics: Why and How to Buy an Air Purifier

If you think that air purifiers are just any other luxury device that your family can do without, read on. You are more likely to discover the benefits of having an equipment that gets rid of air pollutants and improves the quality of the air you breathe.

Why buy an Air Purifier

According to environmental studies, indoor air can be up to five times more polluted than outdoor air. This is because homes and buildings today are designed to keep air inside to avoid heat gain during summer and heat loss during winter. The result is build up of air pollutants that may come from such sources as dusts and mold spores.

The dirty air that circulates in the home can be harmful because air pollutants like dander flakes from pets and tobacco smoke can in fact cause asthmatic and allergic reactions. In addition to this, most people stay indoor and are more likely to inhale polluted indoor air. The effect of dirty indoor air is more damaging to people who are sickly and are more prone to allergies. An ideal option is therefore to ensure cleaner indoor air that is safe for everyone. Reduction of allergens and dirt in the air is best done by an air purifier. Air purifiers clean indoor air and reduce the likelihood of people getting diseases caused by bad air quality.

How to Buy an Air Purifier

Consider the appearance of the unit. This includes the size, portability and the visual appeal of an air purifier. Look for a unit size that suits your area and you are most comfortable with. You may not want to cramp your house with an air purifier that is almost as big and bulky as your bedroom. Consider also the portability of the unit so you can take it with you wherever room you are in. Visual presentation of the device should also match most of your indoor area so it harmonizes with the interior theme and design.

Evaluate the noise level. Look for a unit that does not produce too much irritating noise and one that cleans the air silently. A good air purifier does not only reduce indoor air pollution but causes less noise and disturbance as well.

Check the product specification. You can compare air purifiers by checking the Clean Air Delivery Rating (CADR). A higher CADR means stronger purification power. You should also check the filter specifications because HEPA filter should be able to filter at least 99.97% of air pollutants of 0.3 micrometers in size. Products marked with “HEPA-type” or “HEPA-like” may not meet this standard. Consider also the frequency of filter replacement because the filter itself is expensive and frequent filter replacements may become too costly and burdensome.

Air purifier is not just a luxurious item that your family can live without. In places where dusts, smokes and other allergens can result to bad health conditions, an air purifier is the best option to ensure good air quality and good health.
