Airborne allergens and micro debris are an ugly reality in the air we breathe whether it be at home, at the office, or when we are out and about. Reducing them can help us breathe lighter and fresher and help us manage nasal and lung irritations or annoying allergy symptoms. The thing is, you may not even know how much you are ingesting because 99% of these airborne nasties are way too small to see floating around. You can't control all your environments but the one place, the place where most people spend the majority of their time should be the cleanest so that you can breath 'pure' air most of the time. The most important factors to assess when you are searching for the right unit for your space include the accuracy, accessories, and ease of use. We considered each of this criterion when we put together our list.

Criteria Used for Evaluation

Accuracy

The Clean Air Delivery Rate (CADR) is the rate at which particles are removed from the air, and it is a rating used to assess the efficiency and effectiveness of air purifiers. High ratings signify a much better CADR. The Association of Home Appliance Manufacturers (AHAM) is an organization that performs independent tests on these products to determine how fast or slow they can remove these unwanted particles from the air. To understand the scores, an excellent number would be 350 and a poor number would be around 100 or less. The higher the number the more powerful the fans and the better and more efficient the HEPA filter is. The higher numbered air purifiers are going to do the best job of getting those environmental irritants in the air taken out and at a faster pace.

When you are looking at the space you want to be purified and need to know what coverage is necessary you can check with the AHAM. The AHAM uses the CADR to figure out the maximum square footage a unit is able to effectively purify.
For many home units, the range is anywhere between 4 and 6 which is right in line with what allergists recommend. It is never a bad thing to have more power, but if you are looking for a product that has just the right amount for your breathing needs, this is a good range on an at-home unit.

Accessories

True High-Efficiency Particulate Air filters are the best of the best. They are recommended by the right organizations like the EPA, the American Lung Association, and the Academy of Pediatric Allergy and Immunology. These are the real deal. They can remove up to 99.97 percent of the nasty unwanted particles even as small as .3 microns. These are the best you can get at catching those very small particles like you'd have in the air from pets, dander, and mold spores for instance.

Pre-filters and secondary filters are supplemental to True HEPA filters and they extend the life of the HEPA filter. The pre-filter is a screen that acts as the first barrier or shield for capturing the larger particles that could get caught in the sticky HEPA and congest the HEPA thus reducing its ability to purify. The pre-filter can last for three months before needing to be replaced, washed, or vacuumed.

Secondary filters increase the overall efficacy and also help improve and increase the lifespan of the heart of the purifier, the HEPA filter. This filter takes some of the burdens off of the HEPA and therefore it can work better. Charcoal is a good option for a secondary filter because it can absorb both gasses and nasty odors which may be too small for the HEPA to manage.

Ease of Use

Ease of use when it comes to air purifiers includes the ease at which you can replace the air filters as well as if the design is convenient and simple to understand the operation. The other thing that helps the ease at which you can operate the unit would if the controls are user-friendly, and if there are easy auto settings. Last, features like power-saving modes or the cost of replacement filters all go into the overall ease of use for a unit. If a machine is bulky, hard to move or operate, and doesn't make much sense in use it isn't going to be convenient or helpful and you may opt not to use it as much if it can be a complicated task or a very expensive one depending on the accessories and power needs.

Location is Key

It is important to place your air purifier in an area that is somewhat open around the unit so it can have good, unobstructed airflow in order to operate at maximum efficiency.

Maintenance

Proper maintenance is key for any appliance and air purifiers are no exception. Be sure to follow manufactures instructions for proper cleaning and filter maintenance.

Other Factors to Consider

Value

The amount of money you can invest in a unit can come in the amount of power that it takes to operate as well as the replacement of the filters. It is estimated that the money spent on replacement filters could be anywhere from $25 to $500. For some people that may not seem like a lot but for others on a budget that extra cost is something to think about. Everyone wants to save money so one factor to research is the cost of replacement filters on a model before you purchase the model. There are some filters that can last with regular; ar washings or vacuuming and these can reduce the extra expenditures. Those that absolutely need to be removed after a couple of months and replaced can range in price.

If you have a unit or like one that needs the replacement and you want to reduce the amount of money you spend you may think you can get away with changing the filters less often. Doing this will basically negate the positive effects you intended when you bought the unit in the first place. Not to mention most models will put too much wear and tear on the unit and that could lessen its life causing it to either malfunction or all out fail. Then you have a whole new set of problems because you will be in dire need for a new whole unit, not just a filter. So do yourself a favor and just don't do this. if the manufacturer says to replace in three months, make sure that you listen to the directions and replace no more than the three months recommended time frame.

Instead, if you want to reduce costs, try some of these tips.
1. A clean house is will have cleaner air. The less dust and particles, you have on your surfaces, the less that can move about in the air. The less in the air the easier it is for your purifier to work, and the less stress it has to put out so the filters will last longer and as such, so will your unit.

2. Most people prefer to smoke outside, but if you haven't made that house rule known, start. The cleanliness of the air is greatly reduced with the presence of the toxins associated with smoke. Not only does it smell bad, feel bad, and not sit well in the lungs, but it puts a lot of stress and wear on your filters. So tell smokers, that if they need to get their fix, they need to do it outside. Cleaner air inside the home makes the unit work more efficiently and with less strain so it can last longer.
3. Buy an energy-efficient purifier. Some air purifiers are better at running at low power than others. Granted, you won’t save hundreds of dollars in energy costs by picking an Energy Star unit. Nevertheless, an energy-efficient unit will save you a bit of money in the long run.

Invest in washable filters. If the cost of replacement filters overwhelms you, consider buying a purifier with washable filters. You can reuse a washable filter multiple times.

q: How big is a micron?

a:

A "micron" is the abbreviated or shortened version of the full word, "micrometer." A micrometer is equal to a millionth of a meter (1/1,000,000 meters). This translates to approximately .00004 inches. If you need a visual, a human red blood cell is about 5 microns in diameter, a shaft or strand of human hair is 75 microns in diameter. Bacteria, on the other hand, can range from .2 to 3, so very, very tiny.
