Improve The Air Quality in Your Home With Room Air Purifiers

You need room air purifiers if you wrinkle your nose when you enter your front door. You may notice the pet or cooking odors when you are indoors for an extended time but if you enter from the outside those odors are noticeable.

If there is a smoker in your home, stale cigarette smoke lingers on furniture, drapery and the odor is detectible for days after tobacco was consumed. The odor of fish you cooked for dinner last night doesn't smell as good when it is noticeable the next day.

Room air purifiers can remove those odors as well as clean the air of pollen, dust and dander. Once a product recommended only for expensive homes and business locations, the handy air cleaners are now widely available to the public at reasonable prices.

Quality and Marketing Scams

When a new product is introduced and quickly adopted by the public, you can expect copycats and cheap models to appear for sale quickly. This has definitely been a factor in promotions of room air purifiers.

The units have been available for many years but were not part of the usual group of standard home appliances you might consider buying. There were consumer who swore by their AlpineAir purifiers years ago but it was the environmental protection and conservation movement that led to widespread use of these machines.

In the past ten years the popularity of room air purifiers has grown and a few scammers have jumped on the bandwagon. From $19.95 ionic air cleaners highly promoted through online shopping sites and full page magazine ads, air purifiers have been a visible product now for severa; years.

Perhaps the biggest scams were the units that were extremely cheap but designed to use only one particular replacement filter. The filter itself was far more costly than other (better) filter replacements.

Consumers have become more educated on the topic of room air purifiers. The various types of filtration systems have been tested and compared by leading consumer groups and publications.

Air quality ratings have been adjusted to apply to room air purifiers and these lead to a method for comparison that compares apples to apples. No matter what the advertising hook is for a particular air purifier, the ratings that apply to the unit provide the bottom line for consumers to judge the quality and usefulness of that particular product.

What do You Need?

The choice of what type of unit to purchase begins with clarifying what the homeowner needs to accomplish. For the average home, a simple filtration system that removes many of the particulates and odors from the indoor air is sufficient. For others, concerns about asthma and allergies means looking closer to find the most efficient air cleaning methods.

True HEPA air purifiers

True HEPA filters remove 99.97% of the particulates in the air by capturing particles as small as 0.3 micron. Initially, the drawback for the system was the necessity to replace the true HEPA filter every few months.

In geographic locations where high sand content in the soil or high pollen counts were present, filter replacement was frequently required. Advances in filter technology have led to true HEPA filters that require replacement only once a year. In addition, there are long life filters that can be used for as long as 5 years.

These filters do not decrease in efficiency as they age but actually have been shown to be more effective toward the end of their lifespan. The long life HEPA filters are significantly more expensive but may be worth the cost due to the low maintenance required for such units.

Carbon Filters

A carbon filter alone is not a good air cleaning system. However, the best room air purifiers often use carbon filters as secondary filters to address the odor problems in a room. Carbon has long been known as a substance that absorbs odors. Newer homes with the open floor plans that are so popular allow cooking odors to spread easily through the living area. Carbon filtration will remove those odors quickly as well as the smell of your wet dog or the cat's litterbox.

HEPA Type Filters

Though they are similar in construction to a True HEPA filter, a HEPA type filter is not nearly as effective in removing particulates from the air. These are paper filers and less expensive than their high end counterparts.

In efficiency, they don't come close to matching the True HEPA filters as they do not remove smaller particles. Studies have shown HEPA type filters to be as much as 90% less effective in cleaning capacity. If you are considering room air purifiers that advertise HEPA filtration, it is critical to look closely to see which HEPA filter is used for the unit.

Choosing the Right Products for Your Home

Before shopping, identify the problems you want your new air purifier to solve in your home. The next step is to check the results of testing of some of the major consumer sites and magazines such as Consumer Reports.

Choose the type of filtration system that appeals to you and understand the maintenance time and costs that will be needed for that system. Then make a short list of product manufacturers that offer machines to suit your needs.

Prices can range from $70 to more than $500 for quality products. It is not necessary to buy the highest priced product but buying the cheapest may be a waste of your money as the product may not perform well.


Air purifiers are now in place in homes across the country. By removing particulates and odors from indoor air, these units provide protection from dangerous particles you might breathe into your lungs and also make the air in your home smell fresh and pure.

Remember to get information on the maintenance and replacement costs of the units under consideration. If replacement filters will be required, look online to see if the filters are readily available at a reasonable price.

By choosing carefully, you can purchase room air purifiers for your nursery, bedroom or living room that will quietly improve the air quality in your home for years to come. Identify your purpose in buying an air purifier, measure the size of your room and compare the options available.
