In today's growing metropolitan-based population, clean air is a growing concern, and many are turning to air purifiers. There are some key factors to consider before purchasing just any air purifier. Here are a few tips for finding the best air purifying product for your lung-friendly home.

Types of Air Purifiers

There are actually multiple types of air purifiers. Filtered air purifiers trap particles using a filter cartridge, electrostatic purifiers use a charge, and UV light filters neutralize particles using UV light.

In the filtered category, HEPA filters with 99.97% filtration at 0.3 microns are the gold standard. HEPA stands for High-Efficiency Particulate Arrestance. "HEPA" refers only to those specialized filters capable of removing 99.97% of particulates at 0.3 microns in diameter. "HEPA-type" filters are not the same, and in fact, some HEPA filters may be better than others. Look for data from independent testing labs to better understand the performance of filters in less-than-ideal conditions.

Clean Air Delivery Ratings

The next thing to consider is the CADR or clean air delivery rate, which is the classing system for air purifiers; the higher the CADR, the greater the size of the room the purifier can cater to. There are different sizes and strengths of air purifiers; some may be overkill for a smaller room, or others may be too small for larger rooms. Make sure to buy one appropriate to the space it must clean the air in.

Budgeting for an Air Purifier

There are a wide variety of purifiers and price ranges available in the market. When budgeting for an air purifier, there are other costs to consider besides the air purifier itself.

Running an air purifier 24/7 can add some utility cost, so if you're looking for round-the-clock air purification, it may be more beneficial to purchase a slightly more expensive purifier with a higher energy rating to offset the cost of running the device.

You may also want to consider the cost of filter refills. In air purifiers with a pre-filter, HEPA filter, and carbon filter, the pre-filter can absorb the largest particulates to save the life of the HEPA filter, which is often the most expensive element in the machine.

Finding the Air Purifier for Your Lifestyle

It may be helpful to consider the surrounding environment and potential pollutants that you may wish to clean. For instance, some purifiers claim to remove pet dander, and others are designed for city pollutants caused by construction or motor vehicles. Some purifiers claim to be better suited for people suffering from asthma or allergies. Some are simply more attractive or better suited to the aesthetic of your home!

Look for the "how" and "why" behind these marketing messages to determine which is best for you.

Noise Pollution

Many air purifiers come with a noise level rating. This may be a more important criterion for those intending to spend long hours in the same room as the purifier. To get an idea of what this means, today's average modern fridge has a noise level rating of approximately 50 decibels and is considered acceptable for most living spaces, as it is barely noticeable for the majority of the population. However, there are better noise rating levels for the bedroom or more sensitive ears.

Taking all these elements into consideration, you can find the air purifier best suited to your personal needs, the pollutants you wish to deal with, and any other factors specific to your daily life and environment.
