Guide On HoW To Choose An Air Purifier

How To Choose An Air Purifier

The quality of air can significantly affect your health and well-being. That’s why you should prioritize air purification. For decades, people have been using air purifiers to rid indoor environments of pollutants like dust, mold, pollen, among others. In fact, most people buy such devices hoping to relieve asthma and other allergies. 

Many purifiers are now on the market, making it challenging to choose the right one for your need. Sadly, some of them work fine while others fail terribly. The best choice comes from an understanding of what you intend to use the purifier for. Then, you need to do a thorough research on the types of purifiers and their features.

“What kind of air purifier do I need?” If that’s what you’re asking yourself now, you are on the right track. Air purifiers come in a variety of shapes and sizes and utilize different technologies in air filtration. Figuring out the right one for you may not be that easy at the beginning. 

However, settling the question of how to choose an air purifier that best suits your home begins by determining what you’d want to do with the device. This makes it easier for you to make your decision as you’d be going in the right direction.

Each type of purifier is designed to counter specific types of pollutants better than others. For instance, one device can be great at clearing pet dander but ineffective at removing bad odors from your room. Another purifier can be effective at getting rid of harmful bacteria but have no effect on allergens in the air. 

Therefore, it is important to know the kinds of contaminants you would remove from your house before settling on any type of air purifier. This can guide you in the process of selecting the device that best suits your home’s specific needs. It’s best that you first understand all the different types of air purifiers before choosing one. 

Type of purifier

  1. Room air purifier.This is the only option you have if your home lacks either forced-air heating or cooling. The weight ofa room air purifier can range from between 10-20 pounds. It has a handle for ease of movement and can stand on a table or floor in any space. The purifiers cost from $60 to some few hundred dollars and are great for the removal of allergens. However, they are costly in the long runbecause of the requirement of replacing the particle filter annually. Fortunately, some modern models come with HEPA filters that you can clean and reuse. 
  2. Flat, whole-house air filter.Are you looking for a low-cost option that can work with the built-in cooling and heating unit of your house? Then go forthis kind of purifier. Simply replace the filter of your furnace with one of your choice. The different types of filters include flat filters, electronic filters, ultraviolet filters, and extended media filters. You can replace them after every 1-3 months. They ensure that air filtration is continuous when your fan is running. This is the most efficient option when it comes to filtering household air.  There’s a flat filter in the current heating and cooling unit of your house that keeps large dust particles from reaching the furnace. By replacing it with a pleated filter, it can attract allergens such as pet dander and pollen. The latter filter costs about $15.
  3. Extended media filter. You can build this accordion-shaped whole-house filter into the ductwork of your house. It’s more effective as compared to fiberglass filters in combating air pollutants and allergens because of its shape. The price of media filters rangesfrom between $400-600. The annual replacement cost of the filters is about $40. Media filters require professional installation.
  4. Electronic filters. These are also called electrostatic precipitators. They attract particles such as pet dander and pollen by putting a high voltage charge on them. You can build electronic filters into the ductwork of your house. They cost from between $600-1,000. The filters do not require replacement all their life. All you need is to wash the collector plates with soapy water once in a while. However, the ionization creates trace amounts of ozone. It can also cause lung irritation. 
  5. Ozone generator.You should avoid this type of air purifier. By design, it emits small amounts of ozone. Although manufacturers claim that the byproduct is responsible for reducing allergens like dust, pollen, mold, and smoke, studies show otherwise. Such professions are inaccurate and the ozone emissions could be hazardous. California state has introduced a ban on ozone generator sales because of health concerns. People purchase ozone generators to use them in locations where ozone is a necessity, for instance, in gaseous pollution environments. Other than that, it’s not advisable to utilize them for the removal of allergens such as mold spores, dust, bacteria, and pollen.
  6. Carbon filter. This type is the best air purifier for smoke. This is because a carbon filter is great at removing smells and odors. Whether it is smoke, cooking, mold, or pets that are causing odors in your house, a carbon filter can deal with them and create a fresh atmosphere. It is also the best air purifier for pets.

Considering Different Features

  1. Size. You may be asking yourself, “What size air purifier do I need?” First, consider how big your house or office is. Then chose an air purifier that corresponds to that size. There are purifiers that are small enough to be compact and portable. Others are so big that they take up a whole lot of space. It’s advisable to select an air purifier that can operate in a room that is a bitlarger than yours. This way, there’s a guarantee that the device can eliminate all allergens and still emit fresh and clean air. 
  2. HEPA filter. If you’re looking for filters that can capture air pollutants like dust, mold spores, pollen, and pet dander effectively, then go for HEPA. The best home air purifier consists of this filter. The high-efficiency particulate air (HEPA) filter guarantees the complete filtration of about 99% of all the contaminants. HEPA is the model that doctors recommend the most. The vacuuming of your HEPA filter is possible, that is, you can only replace it once every 5 years. This is in contrast to other types of filters which you may have to do so after every few months.  If you are allergic, avoid buying just any type of vacuum cleaner or purifier. Make sure to purchase an authentic HEPA filter by checking the manufacturer’s noted particulate size.
  3. Servicing indicator. This is a light that showsyou when you should replace or clean your filter. Whether you have a whole-house model or a room purifier, make sure it has a servicing indicator. This ensures the efficient working of your air cleaner. 
  4. Low-noise.Unless you love noises, an air purifier that is loud is not suitable. It’s important to look for a device whose operation functions are quiet. Alternatively, select a model that is designed for larger areas. It can operate better even when the speeds aren’t high, resulting in less noise. 
  5. Easy-to-change filters. There are air purifiers that do not require tools when removing the filter for replacement or cleaning. Others have pop-out doors that allow the easy pull-out of filters for replacement. You should look for such systems. If you choose a purifier that givespeople a difficult task to change, it can put off average individuals including yourself.
  6. Airflow rating. This is a measurement of air change per hour (ACH), that is, the number of times your unit can purify the room in an hour. A purifier that does an exchange every 10-15 minutes is good for your home. The manufacturer’s ACH represents the maximum operating speed that the unit can move at for the maximum available space. This maximum speed makes the purifier noisier. If you prefer running your device with less noise (at lower speeds), then make an oversized purchase of at least 20%. 
  7. Clean-air delivery rate (CADR). This is an efficiency rating that measures the volume of air that the cleaning system filters and delivers. CADR is simply the measure of how fast your unit can remove air pollutants. You need a system that has a CADR that’s above 350. Avoid those with less than 100.

Review the best air purifiers

Some manufacturers make wrong claims on their products’ efficiency. This is where online customer reviews can help you in choosing the right quality of an air purifier. Especially, Customer Reviews and many other websites can give you invaluable information on such purifiers. Read buying guides also and make the right choice.

With the flooded market, it can be overwhelming to make a decision concerning the air purifier that can best suit your home. However, if you understand your needs, the types of purifiers, and their features, then you’re many steps into the right direction. You just need to read reviews to help in making the best purchase decision.
