Deciding on an air purifier for your home or office can be overwhelming. But if you know the features that make for an effective cleaner, choosing the right one can be pretty straight forward. Here are the 5 most important features to have if your unit is to provide the cleanest air possible.
.3 Micron Rating-A micron is a length of measurement defined as one millionth of a meter. This rating is essential to know because it tells you the smallest particles that you can expect you machine to filter. Because a HEPA (or high efficiency particle arresting) can trap and eliminate particles that are.3 microns or greater. The smaller the particulate that a filter can trap, the cleaner the air will be.
Opt for a cleaner that is able to take out particles down to.3 microns. This means that it can effectively remove many of the all too normal indoor pollutants. Dust, dust mites, mold and mildew spores, pet dander, pollen, bacteria and viruses are just a few of the pollutants that this kind of filtration can remove from your air.
Low Noise Level-If you choose a machine that you find too noisy to use, you are no closer to cleaner air. Knowing what the noise level is and whether that is acceptable to you may seem like a small point, but it often becomes a huge issue once the unit is yours. The type of sound it makes is also important. For instance the sound of rushing air is probably more acceptable than the motor sound of a blender or microwave.
Frequent Air Exchange-If you are shopping on line or on foot, somewhere in the technical specifications, either on the website or in a manual, it should tell you how many times an hour you can expect the air to be cleaned. It is essential that you also see the square footage for which this applies. Naturally, the more times an hour the air is the filtered the cleaner it will be. Be sure to match your square footage with the number of square feet the unit is designed to clean.
Steel Casing-Steel is one of the most rugged materials of which a unit can be made. This makes it a suitable match for small children, and curious pets. Steel also means that your unit will not off gas fumes from a plastic casing once the motor heats ups. You want to avoid paying for a cleaner that sends more pollutants into the air in order to function.
24 Hour Coverage-One of the best ways to keep your air clean is to continuously filter it. This means that pollutants are kept at very low levels and are never allowed to accumulate to the point of being unhealthy. Keeping pollutants low makes breathing comfortable for those who may suffer from allergies, asthma, and other respiratory conditions.
This means that the cleaner should be equipped with a motor that can function safely and effectively 24 hours every day whether you are there or not. This kind of motor is called a split capacitor motor. This is another must-have feature to look for in the technical specifications.
