Best Air Purifier: Breathe A Sigh of Relief

Best Air Purifier: Breathe A Sigh of Relief

Breathe a sigh of relief… Imagine coming home to a room that feels light, fresh, and clean. You breathe deeply without a hint of dust or the anticipation of a sneeze. Your family sleeps well, and your kids no longer have those chronic stuffy noses! A quality air purifier is an excellent solution to help improve the overall quality of air in any space.

But, for most of us, this may not be the reality. As much as we care for our home, the condition of the air may not match the hard work we put-in to keep it tidy and neat. Some days you wish you could just take a sponge to every air molecule and scrub the air clean! Luckily there is a better way with an air purifier.

You have probably heard of air purifiers, but wonder if they live up to the hype. Or are they just another household appliance that will sit collecting dust next to that state of the art ice cream maker you “needed”?

We have curated this list to help you understand how an air purifier works, how it can be helpful to you and your family, and what to look for when it comes to features.

Do Air Purifiers Actually Work?

Did you know that pollutants don’t necessarily need to come from outdoors? According to Environmental Protection Agency (EPA), home furnishings, everyday products we use, and even our kitchen cabinets may be the source of invisible, harmful particles. Add to the list second hand smoke, grease from cooking, and residue from cleaning products to see the complex nature of the problem we are facing in our homes and offices.

An air purifier will help filter the air and trap most of the pollutants. While it cannot replace your vacuum cleaner (you still need to do the basics of dusting and cleaning the floors), it can help to reduce allergens, dust mites, smoke, and other airborne particles throughout the air of your indoor spaces.

It is easy to mix up an air purifier with a humidifier or a dehumidifier. Although some brands combine functionality, humidifiers release moisture to the air so you can get a good night’s sleep helping with discomforts of nighttime congestion. Dehumidifiers on the other hand help remove excess moisture from the air to prevent mold and mildew.


Who are Air Purifiers For?

Air purifiers can be helpful to anyone. Even if you do not have noticeable symptoms, poor air quality can have negative long-term effects on your health. (Both Mayo Clinic and Cleveland Clinic have written extensively on this topic)

Typically, air purifiers are most helpful to people who have allergies and:

  • are sensitive to dust, pollen, and other airborne contaminants
  • are sensitive to pet dander
  • would benefit from fewer germs and bacteria in the air
  • if you work in a room without windows and/or fresh air circulation
  • If you smoke and want to clear the air

An air purifier can be especially helpful to parents who are concerned about the well-being of their children. So many young people have trouble getting a good night’s rest. Not many people realize this can be connected in some part to air quality. Kids (and adults alike) are kept up by unnecessary allergy symptoms which leave them frustrated and tired.

On a personal note, my wife uses multiple air purifiers in her doctors’ office in New York City where fresh air is elusive. If you are concerned about not being able to open windows, or air circulation is not great in your office, you may want to consider getting one.

Who Will NOT Benefit From an Air Purifier?

While air purifiers are great for most homes and even office spaces, they will only be effective if used properly. Air purifiers are not for people who like to keep the windows open. This is because air purifiers require a sealed room to function best. Besides, open windows promote effective air circulation themselves.

Air purifiers will not rid of unwanted smells. As an example, they can help remove smoke of the cigarettes, but odor will linger. This is actually the reason why car rental companies and hotels prefer non-smoking customers. The odor can be near impossible to get rid of.

Unfortunately, you will not be able to eliminate or prevent mold with an air purifier. You may want to work with a professional to find the root cause of mold and clean it. Otherwise, your air purifier will be on an endless mission of filtering mold spores…

Types of Air Purifiers

There are a few different types of air purifiers to choose from. Understanding the benefits of each will help you narrow down your choices. You will want to consider price, the space where you will use the air purifier, and your specific health needs.

HEPA Filters Are the Most Popular Type

Coway AP1512HH

HEPA filters (High Efficiency Particulate Air) are the most popular type of air filter. Chances are you have heard of them. These filtration systems essentially use a dense, engineered paper. The paper traps particulate contaminants in the air to improve air quality.

When shopping for a HEPA filter, it is essential to read the fine print. “True” HEPA filters are certified to remove 99.7% of all microscopic particles. However, not all HEPA filters are “true” certified so it is important to look carefully.

The good news is, there are multiple organizations such as AHAM Verifide or ASHRAE that monitor the marketplace to keep us safe.

PROS: HEPA filters are known to be highly efficient. They are easy to find and are help people with respiratory problems including asthma.

CONS: HEPA filters need to be replaced regularly. If you know you are going to forget to keep up with changing the filter, this may not be the option for you. You will also need to factor in the cost. HEPA filters can be pricey. Plus, these filters tend to be noisier than the other options on the market.

Ionic Air Filters Require Maintenance

Ionic filters work without a paper filter. They clean the air by emitting a burst of charged ions. These ions “grab” onto airborne contaminants and pull them out of the air. Science is pretty amazing. Most ionic air filters will include an electrostatic collection plate. This can make it easy to remove particles from the entire room, not just from the air.

PROS: Unlike the HEPA filter, Ionic air filters are simple and maintenance free. You will not need to worry about changing anything out or picking up extra filters at the store. Set it and forget it! Plus, they are known to be very quiet which is important especially in a bedroom or office.

CONS: Some ionic filters pull pollutants to the floor, but do not actually remove them from the room. Models with collection plates require frequent cleaning. So, while you will not have to change filters, you will still need to remember to clean the collection plates to completely remove the contaminants from the space. If you are considering an ionic air purifier, be sure to inquire about how the collection plate works.

Carbon Air Filters Only Focus on Odor Removal

Carbon Air Filters utilize activated carbon. The carbon works to trap fumes, gases, and odors in your space. While they can help refresh a room, Carbon Air Filters DO NOT remove dust particles or other harmful particulate pollution. This is the main difference between carbon air filters and ionic or HEPA purifiers. Carbon air filters can remove odors from things like pets, cooking, smoke, paints, and cleaning supplies.

PROS: Carbon air filters are quite affordable. They do not require a whole lot of maintenance so they are easy to use and can fit into your daily rounds. They can keep a room smelling fresh and clean.

CONS: The downside is that carbon air filters only handle fumes and odors. They are not designed to get rid of heavy particles like dust and construction debris.

Ultraviolet (UV) Air Filter Technology Is Improving

Ultraviolet Air filters (UV) are another option to consider. Instead of trapping pollutants inside of a filter, these filters emit ultraviolet light particles that are capable of attaching to airborne pollutants directly. No need to worry about the UV light! UV light is only released inside the filter unit and does not get released into the surrounding room. It is totally safe for humans and animals alike!

We predict that the next generation air filters will likely combine the UV technology with HEPA and Carbon filtration.

PROS: The perk of these filters is you will never be bothered with replacing the filters. Since they do not require paper filters, you can easily reduce your environmental impact. UV filters create a more sterile environment by reducing the number of germs in the air.

CONS: The UV light on its own is only good for killing viruses, bacteria, and germs. But the good news is UV air purifiers usually come with a built-in HEPA or Ionic cleaner, so you can get the best of both worlds!

Important Features to Look Out for When Buying an Air Purifier

Now that you are familiar with the different types of purifiers and filters and how they can support your needs, you can begin to narrow your search. You will want to consider factors such as the size of the purifier, maintenance needs, storage ease, overall design, reliability, and energy efficiency. Let’s break it all down.

What is CADR? Size and Dimensions

First, consider the space you would like to purify. If you are looking for an at-home option, most air purifiers will do the trick. The majority of air purifiers are designed to be used at home. They are the perfect size to fit on a desk or in the corner of your space without being intrusive.

Just make sure that the air flow in and out of the air purifier is not obstructed.

If you are wanting to purify the air of a larger space such as an office, you might search for a larger model. While larger air purifiers can remove more contaminants, they are usually too obtrusive for at-home use. However, they can be perfect for a large office with space to spare.

This is where the clean air deliver rate (CADR) comes in handy for the industry. Try to select a high CADR rate for a given room size. Here is what the EPA suggests for an average 8-ft ceiling room:

Room Size Min CADR
100 sq.ft. 65 cfm
200 sq.ft. 130 cfm
300 sq.ft. 195 cfm
400 sq.ft. 260 cfm
500 sq.ft. 325 cfm
600 sq.ft. 390 cfm

If you have higher ceilings simply choose an air purifier with a higher CADR rate.

Regular Maintenance (& Maintenance Costs)

It is important to consider not only the upfront cost of any new appliance, but also the long term maintenance cost and needs of the tool. Depending on the type of air purifier you choose, your maintenance needs will vary. You will want to consider your budget and your time.

Air purifiers with physical filters, like a HEPA filter, need to be changed out more often. As a result the cost can start to add up over time.

While ionic air purifiers with built-in collection plates do not require you to buy filters on a regular basis, they do require a more complicated cleaning process so you will want to be realistic about your schedule and what you can keep up with.

air-purifier-noise

Are They Loud?

Noise is another factor to consider. Some of us are more sensitive to low-level noise than others. Typically the noise of an air purifier at 24 – 54 dB, does not bother most people. However, you might notice the sound more at night when the ambient noise level is different.

Most people can sleep while the air purifier is working. Many even like to have the gentle noise. However, you will want to consider noise level if you are a light sleeper and plan to have the air purifier in your bedroom.

In general, air purifiers are much quieter than top of the line quietest dishwashers.

HEPA filters and carbon filters use a fan mechanism to drive air through the unit, so they tend to make more noise. The operating speed of the fan will also affect the volume.

Ionic air purifiers are great for people looking for quieter machines. If you buy an air purifier that is too big for the room it is intended for, it will likely be too loud. So, size is important to consider not only for space reasons but also for noise.

Will My Energy Bill Go Up Significantly?

Air purifiers need to be running continuously to be effective. If you turn it on and off, it will not do its job properly and you will not get the air quality results you are looking for.

Since it needs to run all the time, you need to pay attention to the energy efficiency of the unit before you buy it. If you do not, you might end up with an air purifier that cleans out your air and your wallet. You will find that most air purifiers adjust their level of operation based on the pollution level in the air to limit energy use.

Home air purifiers can range from 5 watts to 200 watts of power. We consider between 50 watts and 100 watts to be in the acceptable spectrum. Energy Star appliance ratings will typically fit in this profile.

Reputable Manufacturer

There are a lot of new air purifier companies on the market, and not all of them are turning out high-quality machines.

However, some newer companies like Bluair and Partu are doing a good job.

When in doubt, trusted brands like Honeywell, Dyson, and Conway tend to have a track record for the best warranties and customer service support teams. In addition, choosing a product from a reputable brand can offer convenience. It will be much easier to find original manufacturer filters and parts.

There is a wave of new companies from overseas or Kickstarter. It is not usually the best idea to be one of the first people to buy an air quality product from these companies. Be sure to look for longevity in the market.

Type of Pollutant or Particulate

You already know that all air purifiers are different by design. But, they are also different because they often target different pollutants or particulates. Some are specifically designed to remove dust and debris from the air. Others are intended to reduce microscopic biological contaminants like germs and bacteria.

You will want to choose your home air purifier based on what type of pollutant you are trying to remove.

FAQs

Q: Are air purifiers a waste of money?
Not if you are looking to improve your Indoor Air Quality. You can consider it an investment in your health.

Q: Do I need one in every room?
Air Purifiers are designed and sized to clean the air in an individual room. Using multiple units in a household can be effective, but it might be more effective to buy a larger unit.

Q: Where should I place the air purifier?
You should place the air purifier close to the source of potential contaminants, whether it is odors, fumes, or pet dander. Be sure to avoid tight spaces and corners. You may want to place your purifier near room entryways. Keep your purifier away from TVs, microwaves, and stereos in order to avoid wavelength interference. Make sure the windows in your space are closed. Opening a window definitely will not help with indoor air quality (IAQ).

Q: Why are good air purifiers so expensive?
The best air purifiers utilize high density particulate filters. It is possible to get these for cheap, but cheaper filters have a lower capacity and will remove less pollutants from the air. In most cases, you get what you pay for.
