How to Choose a Quality Air Purifier?

As mentioned earlier, choosing the right air purifier yourself can turn into a hefty task if you’re not sure what to look for. Like every product, air purifiers have some key features that need to be considered before buying one.

Type of Filtration

Air purifiers use different types of filtration. The most common ones are HEPA and Carbon Filtration. Both filters are used for different types of air purification. HEPA is the right choice if you just want generally cleaner air, while a carbon filter is more efficient at removing allergens from the air.

Area of the Room

Different air purifiers work efficiently in different sizes of rooms. You need to evaluate the size of the room where you wish to use an air purifier and choose one that is best suited for that size.

Budget

Keep your budget in your mind while you look at all your options. The price of an air purifier may greatly vary from roughly $20 up to $1000. Still, you do not necessarily have to spend a fortune for a good air purifier. Provided you look at the right features, a good quality air purifier can be fit into any budget.

What Does an Air Purifier Do?

An air purifier, in very simple terms, is an air cleaner. What it does is removes various contaminants from the air in the room where it is placed, thus improving the quality of your indoor air.

Air purifiers are most beneficial to those who have allergies or asthma as they remove various allergens and irritants from the air. These devices also work really well at removing cigarette/tobacco smoke from the air and reduce the effect of passive smoking.

How Does an Air Purifier Work?

Air purifiers work just like sieves, only much smaller. Just like sieves, all the bigger and unwanted particles are removed from the filtered medium. The devices use these fine-sized sieves to filter the air as it circulates through them.

Some devices use additional features to enhance their air purifying functions. These features may include an electrical attraction for the particles to trap them, or an ultraviolet light system with the capability of killing a number of microorganisms. Such a light system not only keeps the air purified but also saves the filter itself from being contaminated by unwanted germs.

Aspects to Consider Before Buying 

Here are some things to keep in mind while shopping.

CADR Ratings

Air purifiers are rated using Clean Air Delivery Rate (CADR) that enables consumers to gauge a unit's effectiveness for particular room size. The higher the CADR rating, the more the air contaminants the purifier can eliminate and the bigger the area it can clean. Therefore, your aim should be to get a purifier that can efficiently clean the air in your space within the shortest time possible.

Filter Types

The American Lung Association recommends the use of True HEPA filters for standard air purification. Therefore, you may prefer to have a HEPA air purifier to capture up to 99.97% of minute air airborne particles like dust mites, dander, or pet hair. Some air purifiers have additional air cleaning steps, such as a UV light, charcoal filter, or carbon filter.

A UV light destroys bacteria, viruses, and mold spores, while a charcoal or carbon filter is better for trapping odor and VOCs (Volatile Organic Compound). For all-around indoor air quality improvement and protection, you can choose a filtration system that utilizes all three filter types.

Noise Levels

The noise levels of different air purifiers range between almost quiet to steady humming, similar. Most consumers prefer a unit that is as quiet as possible while performing at optimum speeds. 

Types of Air Purifiers

The many types may be confusing. Here is some information to help you out. 

What is an Ionizer Air Purifier?

An ionizer air purifier is one that uses the chemical properties of ions to clean the air. These air purifiers create negatively-charged ions using electricity. These anions are discharged into the air to attract positively-charged contaminants and bind them down.

After binding, denser particles that are too heavy to float in the air are formed. The dense particles fall to the ground and thus lower the chances of being inhaled. They can then be cleaned through wiping, sweeping, or dusting.

What is an Ozone Purifier?

Ozone air purifiers eliminate strong odors and clean the air by creating ozone. These purifiers work by taking in oxygen from the natural air and giving it a strong electrical charge. The electrical charge forces the oxygen molecules to form O3, which is the ozone that rids the air of contaminants. 

The air purifier releases the ozone into the air. When it hits any air contaminants, the third molecule of the ozone gets attached to the molecule of that contaminant then eliminates it. When ozone attaches to odors, bacteria, and germs, or any pollutants while at the molecular level, it works by destroying the cell wall of the contaminant. This process eliminates the contaminant, after which the ozone particle reverts to oxygen. Ozone purifiers are useful in removing mold, smoke, and other pungent odors.

How Do Air Purifiers Compare?

Air purifier, dehumidifier, humidifier, air scrubber, which is best for you? Check out these helpful comparisons. 

Air Purifier vs Dehumidifier

Similarities

Both air purifiers and dehumidifiers reduce allergens in a room, improving the room air quality.

Differences

An air purifier filters and circulates air by capturing smoke, dust, pollen, and different types of allergens. The purpose of the dehumidifier is to minimize the moisture content in your surrounding air. Dehumidifiers eliminate microbes and molds that thrive in a moisturized environment.

Alen BreatheSmart Air Purifier

Air Purifier vs Humidifier

Similarities

Air purifiers and humidifiers help with the reduction of allergies, asthma, eczema, and cough.

Differences

Air purifiers clean the air by capturing dust, allergens, mold, smoke, and controlling odors. They have different types of filters that capture the air contaminants hence improving air quality.

On the other hand, humidifiers are designed to control the humidity level in the air in your room hence they do not have any role to play in the number of contaminants in the air. Instead, they release moisture into the air, consequently increasing the room's humidity level.

Air Scrubber vs Air Purifier

Similarities

Air scrubbers and air purifiers have the primary function of cleaning up the air in your space. Specifically, they clean up the air by eliminating various contaminants that cause air pollution and discomfort. They both use filters to clean air.

Differences

Air purifiers utilize advanced filters with your central air unit or HVAC to filter the tiny particles and air contaminants. They essentially sanitize the air by eliminating up to 99% of the pollutants by trapping them within the different types of filters.

Air scrubbers use the search-and-retrieve mechanism in eliminating air contaminants. Air will flow through the ductwork system and pass through filters to eliminate pollutants before being allowed back in the space. 

Benefits of Investing in a Great Air Purifier

An air purifier may seem like an item of luxury, but given the present era, it really isn’t. It is quickly turning into a device that one absolutely needs to have for one reason or the other. And investing in something that brings you a bunch of benefits is a no-brainer.

Better Quality of Life

The air that you breathe in has a huge impact on not just your mood, but also on the quality of your life in general. Breathing in fresher air will automatically put you in a better mood and make you feel more energized.

Helps With Allergies

An air purifier works wonders to help you with your allergies. An efficiently working air purifier will remove most of the allergens from the air, leaving you free from the struggle of dealing with constantly triggered allergies

Reduced Smoke

If you live with someone that smokes, then an air purifier will greatly decrease all the effects of passive smoking that you may be suffering from. Not just that, any sort of smoke that is in the air surrounding you indoors will be reduced greatly, leaving a positive impact on your health.

Most air purifiers use True HEPA filters that can remove up to 99% of air contaminants in the air. Air purifiers are about 99% effective in cleaning your indoor air. To improve the quality of the purification further, you can use different types of air purifiers. For example, while the HEPA filter air purifiers are good for eliminating contaminants like dust and pet dander, air purifiers with carbon filters are good for cleansing the air of odors and musty smells.

How Long Should I Keep My Air Purifier On?

It is highly recommended that your air purifiers should be on all the time. This is because air purification is a continuous process, and the air quality in your space changes all the time, and would need cleaning more regularly for maximum results.

However, it is advisable to let your air purifier rest for a few hours after prolonged use to boost its longevity.

What is an Ionizer on an Air Purifier?

Ionizers in air purifiers emit negatively-charged particles called anions that help the purifiers to capture contaminants in your space.

The anions attract and bind down the positively-charged contaminant particles and cause them to drop to the ground or on other lower surfaces to reduce the chances of inhaling them. They can then be eliminated by regular dusting, wiping, or cleaning.

Are Air Purifiers Safe?

The safest air purifiers are the ones that are filter-based because they do not produce any harmful by-products. Ionizer air purifiers are also relatively safe as they only produce ozone as a byproduct. Ozone purifiers are potentially unsafe because of exposure to ozone. To reduce the chances of exposure to ozone, it is important to leave the room for the duration the purifier will be working and also for about 60 minutes after it stops. This allows time for the ozone molecules to dissipate or revert to oxygen molecules such that the air is fully safe all over again.

Can Air Purifiers Remove Viruses?

When used appropriately, UV, ionizer, and ozone purifiers can remove viruses from the air they involve either the production of heat or the release of anions and ozone that are capable of controlling the viruses in the air but only at that specific time when they are on. The heat and ozone destroy the envelope proteins in viruses, hence killing them off.

The anions bind down the viruses and make them too heavy to float in the air. HEPA purifiers may have the ability to trap viruses depending on the size of the virus, but they cannot kill the virus. As such, the virus may remain on the filter for hours or days and may eventually find its way back into the air. 

Do Air Purifiers Remove Odors?

Most air purifiers are majorly designed to minimize air pollution by capturing air contaminants. Odors can be removed if the purifier has activated carbon filters, which are efficient in capturing the tiny particles that cause smells.

My name is Bob Wells and I am a retired HVAC tech from Washington state. I am currently retired and no longer do much with HVAC, however, I feel like I have a lot of knowledge in the subject and I wanted to create a website where I could talk about what I've learned and help upcoming HVAC techs.
