Indoor air quality is one of the most important to maintain a healthy home, or even an office. With this, it is easy to understand why a lot of people invest in the best air purifier, which can be beneficial in more ways than one. It cleans the air that we breathe and also eliminates foul odor. It gets rid of airborne pollutants that would otherwise be harmful for our health.
If you are thinking of buying an air purifier, keep in mind that they are not all the same. You should take a look at the technical specifications, and more importantly, consult with air purifier reviews. By doing such, it will be easier to weigh the pros and cons of the alternatives that you will be confronted with, increasing the likelihood of making the right decision.
Features of Air Purifiers
Filter Type
As you read through reviews about air purifiers, you will find there are several purifier filter types available. Included in these are: carbon filters, HEPA, ultraviolet and ionic. You’ll find that some purifiers utilize only one type of filter while others will often have a combination of two different types.
- HEPA is the abbreviation for High Efficiency Particulate Air. In order to be a HEPA certified filter, it must be 99.97% efficient at removing dust mites, pollen, dust and pet dander. HEPA purifiers are highly recommended by Allergists and doctors due to their ability to remove contaminants that are harmful, down to the microscopic level. These filters must be replaced every year, so you will want to know how much the replacement cost will be for the particular model you have chosen to purchase.
- There is a unique technology involved with Ionic filter models (also known as ionizers). A negative ion generator is used with air ionizers. The generator sends out negative ions into the air, which in turn will attract positive particles, like allergens and dust. As the two ions come together, the resulting particles become quite heavier, which causes them to fall out of the air and on to the floor. There are ionic filter purifiers which contain a metal plate with an electrostatic precipitator that will collect these particles. This plate must be regularly cleaned in order for the unit to work properly. If this is the kind of unit you are considering, be sure to keep this in mind.
- Ultra Violet (UV) purifiers are a little different as that they do not use a filter in order to remove contaminants from the air. Through the use of ultraviolet light, the molecular bonds of DNA in the harmful pathogens and bacteria, which are floating in the air, is broken down, thereby killing them off. These units are quite efficient at killing molds, harmful yeast, bacteria, and viruses. However, the dust and allergens are not removed from the air. Because of this, this method of air purification is best utilized in conjunction with another filter type.
- Carbon filter are usually found combined with another filter type and used as a pre-filter. They are extremely efficient when it comes to removing the particulate contaminants found in chemicals, gases, smoke, and those associated with odors.
Area Coverage (Room Size)
No matter which of the technologies you will be using, it is extremely important that you consider the area which the air purifier will be used in. You want to make sure that it is able to work efficiently in the square footage of the space it will be utilized for; check the square footage listed on the device.
If you’re not sure how to calculate the square footage use the square footage calculator.
Air Changes per Hour (ACH) Rating
This is a rating given to air purifiers that lets you know how frequently air within a room is exchanged. If a unit has an ACH rating of six, this means that it is able to exchange all the air in its maximum area of coverage six times every hour. Asthmatics need to have a rating that is at least four, but it is preferred to have a rating of six or eight.
Clean Air Delivery Rate (CADR) Rating
How well air is purified by a given device is indicated by its CADR rating. The Association of Home Appliance Manufacturers (AHAM) is the organization that calculates this rating. Units that have been tested against the standards of the AHAM will also have a seal of certification. This rating is of importance when you are considering a particular air purifier because it will let you know precisely how efficient the unit is at removing three particular air contaminants: tobacco smoke, pollen, dust.
Noise Level
For many people wanting to purchase an air purifier for home use, the amount of noise produced by the unit is of great concern. It would not be very practical to have a unit that is extremely noisy if you plan on placing it in your bedroom or living room. Likewise, if the unit is being purchased for a warehouse, or a large business, then noise level may not be much of a factor, and a more powerful louder unit may still be quite acceptable.
The decibel levels of most units are listed on the package. By using the chart below, you will be able to see how loud it may be as compared to sound you are more familiar with.
- 10 dB – Breathing
- 20 dB – Rustling Leaves
- 30 dB – Quiet Library
- 40 dB – Raindrops
- 50 dB – Average Home
- 60 dB – Normal Conversation
- 70 dB – Inside a Car
- 80 dB – Phone Dial Tone
Energy Usage
Air purifiers are not like most other appliances as they are continuously run throughout the day. When thinking about purchasing an air purifier, you may have concerns as to how much your electric bill may be increased. What you will find out is that the majority of purifiers operate on very little electricity. The majority of units utilize somewhere between 50 to 300 W of electricity. As a comparison, a standard light bulb uses 60 W, and 350 W are used by most computers.
Here is a little sample of energy costs and usage: an air purifier that uses 175 W, operating 24 hours every day, for an entire year, would cost approximately $12.50 each month, or a total of $153 annually to operate. If you are still concerned over cost, we would suggest looking for an Energy Star Certified unit that best meets your needs. These units are 40% more efficient than the standard models which can save you approximately 230 kW per hour every year. This would result in a savings of $25 from your electric bill. It’s a good idea to always look for this rating when you are reading reviews on air purifiers.
