• The reasons you might need an air purifier
• Decide on the size you will need
• Review the features for each
• Know where you will place your air purifier
• Realistically evaluate how much maintenance and upkeep will be needed

Backing up all the Selective

Finding the top-rated air purifier is not rocket science. Our tests involved checking the noise levels that an air purifier releases while in action, and the average range for optimal use. We used each unit that we tested in the bedroom, living rooms, offices, and other spaces of varying sizes then compare the operation.

It is our joy to inform you that we have taken each unit in this review through thorough tests. Therefore, the information given is sufficient to help you make an informed decision when getting your air purifier.

Here are some of the factors that you will need to consider carefully:

Noise Level and Energy Consumption

These are two key points that most manufacturers avoid mentioning on their websites!

The noise levels that an air purifier produces depends on how well air flows in the unit. The higher the rate of airflow, the higher the levels of noise. If you do not want a unit that is too loud, then you might want to go for one with an adjustable rate of airflow. Almost all of the units that we have discussed in this review have a noise level of 5 and 60 dB, so they are quite tolerable.

The most manufacturer also avoids talking about energy consumption. The good thing is that most air purifiers have low energy consumption levels, and with normal use, you should not see hikes in your electricity bill.

Reliability and Sturdiness

Whenever you are considering making an expensive purchase, reliability is a key consideration where you should not make a compromise.

In this review, we have objectively and independently compared solid and reliable air purifiers, so that your investment is worth it. All the purifiers discussed have proven strength and reliability in their use based on the customer reviews and backed up by our tests.

Suction Capacity

An air purifier’s suction capacity determines how effective it will be. An absorption capacity of say 10,000 feet per hour will purify the air in an 800 square feet space in one hour. Make sure you consider this feature!

Maintenance

How often will you be required to replace the unit’s filter? Are you up to it? Some filters require frequent replacement, while others are permanent. Other models have a filter replacement or automatic cleaning indicator, which are very reliable. Keep all these in mind.

The technology of the Air Purifier

The main technology that differentiates between the best and basic air filters is the filter system, and this what determines how effective the unit will be in air sanitation. There are four filter technologies that categorize air purifiers.

1. Filter Purifiers

In this technology, air purification goes through a couple of filtration stages, and mechanical filtration occurs in each. The air purifiers today have three filtration stages.

The pre-filter has an inert foam that specializes in capturing large, visible particles. The activated carbon filter removes volatile organic compounds and destroys odors. Finally, the HEPA filter is great at removing up to 99 percent of molecules as tiny as 0.3 microns. With these three filters, you can be sure of deeply clean and pure air. However, this technology requires regular filter replacement for proper operation.

2. The Purifiers Photocatalyst

This technology constitutes of a catalyst, mostly Titanium dioxide and operation require UV radiation. This air purification system oxidizes polluting particles, transforming them into carbon dioxide, water, and nitrogen.

3. Ionizers Purifiers

This technology generates negative ions that merge positively charged or neutrally suspended particles. The particles will, therefore, become too heavy to remain suspended, and they fall to the surface. The operating principle of such purifiers is electrostatic operation.

4. Plasma Air Purifiers

These act on the air, releasing oxidative molecules that capture air particles through a magnetic field. However, this technology is not popular because it releases free radicals and air ozone that are harmful.
