Health and the environment are among the first hot debated issues in our society. That’s why air purifiers have recently been taken into big consideration. After an in-depth understanding of air purifiers’ features and functions, you are surely wondering how to choose a perfect air purifier for your own. A good choice of an air purifier depends on a variety of criteria listed below.

Today we will help you how to choose an air purifier wisely and easily.

Types of air purifier

There are 3 main types of air purifier: Ionizers, HEPA Air Purifiers and Air Sterilizers.

Ionizers

choose an air purifier

Ionizer air purifiers are generally the cheapest, but the least effective because they simply make the particles fall to the surface in the room, resulting in a polluted atmosphere. The air might be fresher, but the pollutants are still in the room and turn back to the environment, which offers no help at all. In general, an Ionizer itself is not the most effective way of cleaning your room, but an Ionizer as a part of a HEPA Air Purifier is a good idea and more common nowadays.

HEPA Air Purifiers (High-Efficiency Particulate Air)

HEPA Air Purifiers (High-Efficiency Particulate Air)

HEPA Filter air purifiers offer better air cleaning efficiency than Ionizers. The contaminated air is sucked into the machine and goes through the HEPA filter by a fan. The filter collects over 99% of the contaminants and pulls the cleaned air back to the room. The distinctive feature of a good HEPA air purifier is its ability to filter a huge amount of airborne contaminants for a relatively low cost. The Blue air range of HEPA Air Purifiers seems to be the most powerful, quiet and energy-efficient unit you can buy. With HEPA-based machines, you need to replace the filters regularly to keep the air clean all the time.

Air Sterilizers

Choose an air purifier

Air Sterilizers help to clean the air to the maximum degree when it comes to the most harmful pollutants like viruses and bacteria. They are also completely silent in operation and have no filters to replace. One disadvantage is that it shouldn’t be moved regularly as it takes too long to restart after being repositioned. Another weak point is that this model is not designed to remove large and heavy particulates. In summary, choose an air sterilizer if you are concentrating on one specific room such as a bedroom, wishing for silent operation and finding the way to destroy viruses, bacteria, and other weightless pollutants.

Cost of replacement filters

Normally, there are two types of filters: washable and non-washable. For washable filters, you need to remove and clean regularly on the main basis whereas non-washable ones should be replaced periodically. Ideally, it should be every 6 to 12 months for pleated filters and every 3 months for activated carbon filters. Almost every air purifier has an indicator that lets you know when the filters need to be changed or cleaned. The costs of filters vary widely, but for the large design of air purifiers, they range from $20 to over $200 per one. Filters with odor-removing carbon can cost $50 on average.

Certifications (CADR rating)

Certifications (CADR rating)

In terms of certifications and qualifications, there are some commonly noted labels that you should be looking for on the packaging of the purifier. The first one is the Energy Star logo. Air purifiers must run ideally 24/7 to be at the best effectiveness. Air purifiers certified by Energy Star are 40 percent more energy-efficient than standard models. 

The users may also see an AHAM Verified seal, which means the Association of Home Appliance Manufacturers has already tested the model. Many air purifiers have undergone AHAM’s certification program, which provides clean air delivery rates (CADRs) and room size guidelines on the seal.

CADR index shows the volume of fresh air that an air purifier produces at its highest speed. The higher the CADR index, the more efficient the air purifier performs. Air purifiers with HEPA filters often achieve the highest CADR. There are different CADR ratings for removing tobacco smoke, dust, and pollen. When considering this factor, you should focus on your main concern of pollutants. For example, if you live with a smoker or use the fireplace regularly, choose an air purifier that has a high CADR rating for tobacco smoke. 

Room size

If an air purifier has an AHAM Verified seal, it can show the suggested room size. You can check out the ratings to see what room-size range is suggested for each model based on its test results. Most of the models at present are suitable for large rooms (350 square feet and up) and the purifiers still work well at lower speeds when you’re watching TV or sleeping.

Noise

Noise might not be among these above-mentioned factors but it is relevant to the topic. Our air purifiers are suggested to be running day by day, so ideally they should also be quiet enough to avoid disruption. You may find how many decibels a model operates at on its packaging or website listing. 

One tip for minimizing noise from an air purifier is to adjust the unit on the high setting when you’re out and turn it down to low when you’re in the room. Besides, you can buy an air purifier for a larger area so that even at a low speed, it filters more air.

Budget

Financial situation

If you are worried about your budget, Ionizer air purifiers will be the most suitable choice, as above-mentioned. However, if you just pay attention to the quality and money is not a problem, don’t hesitate to look for an Air Sterilizer or a HEPA air purifier. These are much higher in quality and energy efficiency. Additionally, HEPA air purifiers are still at the top list on the market. 

Summary

It seems that people are becoming increasingly aware of the need for clean air. With all these tips above, a customer must be much more confident in choosing the best air purifier on the market. One thing to remember again: in any case, you ought to choose an air purification solution that best meets your needs.
