Air Purifiers For The Home

Complete Guide to Air Purifiers

Pollen, dust, pet dander, mold… all of these things can cause many people to have a miserable day. Some of it can be found outside, while there may be a bit more inside than you think—a lot more. Millions of people suffer from allergies every day, from coughing and sneezing to nausea and breathing problems. Mold can be especially difficult to deal with.

While outside might not be easy to deal with, there are plenty of things that you can do for your home. Air purifying is one of the best methods to keep your house’s air fresh. It can take out all the allergens from the air and make your rooms comfortable to be in, even if you have pets. There are plenty of ways to do this, from negative room pressure, to getting simple dehumidifiers to take the moisture away.

What Are Allergens?

Allergens are basically substances that cause allergic reactions in people. Millions of people are allergic to at least one thing, and these substances can cause anywhere from a slight itch to anaphylaxis, which is a deadly swelling that can block off breathing or blood circulation. The latter is usually caused by food allergies, but it depends mostly on the person.

Some common allergens are:

  • Pollen
  • Dust
  • Pet Dander
  • Mold
  • Food and Drink (mainly nuts, fish, and dairy)
  • Some Drugs (penicillin, sulfonamides, salicylates)
  • Insects

While air purifiers won’t work on some of these, many people have to stay away from these things. Usually, the first four in this list only cause mild irritation like watery eyes, sneezing, coughing, and sometimes rashes. However, there are things that you can do to avoid these allergens as well. You can’t escape some of them while outside, but you can control the interior of your home.

What Are The Symptoms of Airborne Allergies?

If you're not sure whether you're affected by any of the airborne allergens listed above, there are a few symptoms that you can look for.

  • Sneezing, accompanied by a runny or stuffy nose
  • Coughing
  • Post-nasal drip
  • Dark circles under your eyes
  • Watery eyes
  • Conjunctivitis

These are good signs that you have allergies to something, especially one of the things listed above.

Symptoms of Mold Allergies

The most serious airborne allergen, however, is mold. Mold can cause many different types of health problems and it can be hard to detect, because its symptoms so often look like just normal allergy symptoms. If you want to know whether your body is reacting to mold or not, here are some symptoms of mold exposure.

  • Runny or stuffy nose
  • Dry, scaly skin
  • Nose bleeds
  • Fatigue
  • Muscle cramps
  • Memory issues
  • Coughing
  • Diarrhea
  • Joint Pain
  • Headaches
  • Light Sensitivity
  • And more…

If you experience any combination of these symptoms that hasn't otherwise been explained by your doctor adequately, you may be experiencing prolonged mold exposure in your home or work and not realize it.

While an air purifier can help reduce these adverse effects substantially, the source of any mold growth must be removed to solve the problem permanently.

Mold Remediation

Air purifiers are key when it comes to mold remediation. After mold has been removed from the source, they are necessary to clean the air of the mold spores. Whether it’s on a wall in a bathroom or in a basement, spores are released in the air. Mold experts usually bring in commercial-sized or industrial air purifiers to help clean it.

If the entirety of the mold isn’t removed from the air, there’s a possibility of it growing back. Air purifiers are also a good temporary fix if you think you have mold in your house. They will constantly clean the air for you from the mold spores, but keep in mind that it’s just that: temporary. You’ll need to get a mold expert into your home as soon as possible to remove it.

What Are Air Purifiers?

Air purifiers are, at their core, things that filter out impurities like allergens. While most of the air we breathe has many gasses in it, those small particles will make your day rough. Dust, pollen, and more will screw up your sinuses and breathing in the worst kinds of ways. Air purifiers, whether it’s a mask, a small desk gadget, or a big, industrial machine will take these particles away.

There are many different types of air purifiers, but there are usually four categories that they will fall under:

  • Carbon Filtration
  • HEPA Filters
  • UV Light
  • Ionizing and Ozone Generators

Each one has its own special method of purifying the air and some are stronger than others, but they also do specific things. Each one has a filtration system that may or may not be beneficial to you, so it’s always a good idea to research them before making a purchase. We’ve narrowed down a few of each type to assist with your decision. Some of them have mixtures of the filters.

Carbon Filtration

This type of filtration has been around mainly for water and has only recently come to air filters in the past decade or two. Using activated carbon, the minerals absorb chemicals and other impurities from the air through chemical attraction. For use in carbon filtration, it is extremely processed to make it more porous than normal, making it more absorptive.

There are many benefits of using a carbon filtration system, including:

  • Can absorb almost any vapor and many chemicals and molecules.
  • High absorption capacity, making it last for a lot longer before needing to be replaced.
  • Functions in a large array of temperature and humidity.
  • It is completely safe.

There are very few drawbacks, but there are a few. For example, the amount of carbon is crucial to how much it can absorb. A smaller, portable air filter may not pull as many impurities as you’d like or need it to, but a larger one would certainly do the job.

Blue Pure 211+ Air Purifier with Carbon Filter

While fashionable and compact, this carbon filter air purifier is one of the best on the market. It goes well with most furniture sets and is one of the top-rated ones among customers. The fan is completely quiet and captures 99% of airborne pollutants like dust, mold, pet dander, and other allergens. It works well in any room and has two other filter mechanisms aside from the activated carbon.

This air purifier goes through one filter in about six months. The filters can be somewhat expensive, but this machine makes them last longer than normal. These machines are somewhat large, but when it comes to carbon filtering, bigger is better.

Green Air Purifiers HEPA and Carbon Filter Air Purifier

Another option for those that want carbon fixtures, this air purifier contains HEPA filters along with the carbon filters. Boasting IonCluster technology to attack airborne microbes and kill bacteria, this air purifier is one of the top air filters as well.

It is extremely quiet and is energy efficient with an air quality color-changing light that shows indication of filter status. The BluePure purifier is sleek and modern and can go in any room in the house with four different operating modes: auto, night, fan, and silent. It can cover up to 1000 square feet of a room.

HEPA Filters

High efficiency particulate air (HEPA) filters have been around since the 50’s. They are standard when it comes to air purification and are found in quite a few of the other air purifying machines. These filters are government-regulated to state that 99.97% of particles that have a size of 0.3 micrometers must be caught by it. There are four primary filter collection mechanisms:

  • Diffusion
  • Interception
  • Intertial Impaction
  • Electrostatic Attraction

With these processes, there is hardly any escape for allergens. These filters are so widely used that they are also used in prevention of the spread of bacterial and viral organisms. They are used in hospitals to protect staff on many occasions. Airlines and motor vehicles also use these types of filters.

Alen BreatheSmart Customizable Air Purifier with HEPA-Pure Filter

This large HEPA filter air purifier is one of the most customizable on the market. With over 15 colors to choose from, you can be sure to find one that matches your room perfectly. However, not only are the colors customizable, the filters are as well. You can choose to four different types of filters in it: for dust and allergens, mold and germs, smoke and VOCs, and even pet and diaper odors.

It is almost silent and has a smart sensor feature, which automatically detects air quality. This extends the life of your filters tremendously and can save you a lot of money in the long run. It is energy efficient with only a 120V power supply with 105 watts on its highest speed.

Rabbit Air HEPA Air Purifier

It has a four-stage purification method and goes through both HEPA and charcoal-based activated carbon. This purifier can last up to three years with 12 hours of daily operation. It is quiet and almost silent at low speed while not taking very much energy.

The four stages of this air purifier is the pre-filter, which is washable, the HEPA filter, a charcoal-based activated carbon filter, and even a negative Ion generator. It even has a childproof feature that pauses the purifier if the front panel is removed. There are a few different colors to suit your preference and it can go in any room in the house.

UV Light Air Purifiers

While UV lights aren’t the most powerful air purifiers on the market, there are quite a few that actually work well. However, there are many that don’t. Along with negative room pressure to isolate rooms, hospitals also use UV lights to help purify air. Ultraviolet lights are stronger than the visible electromagnetic waves and will destroy microbes in the air on contact.

Some air purifiers are combined with UV light to better filter, but those with only UV lights do not have to deal with filters. The lights eliminate the allergens and microbes out of the air, removing them completely, practically making them disappear. It can make your rooms a bit brighter than you’d like, but it’s an effective method.

PureZone HEPA Air Purifier Plus UV-C Air Sanitizer

While not specifically a UV light air purifier, this HEPA air filter is combined with a UV-C air sanitizer that will further eliminate air pollutants like dust and pollen. It goes a step further to eliminate germs, bacteria, fungi, and viruses with the UV light, making it twice as effective as some HEPA-only air purifiers.

The air purifier itself is very quiet and is easy to operate. It has light-touch buttons that make it operate in the easiest fashion. The machine is simple to set up and has an automatic timer if you don’t want it to work continuously. It comes with a 5 year warranty and 7-day customer service in case anything ever happens to it.

SereneLife Air Purifier Hepa Filter with UV Sanitizer

This is another HEPA-type filter air purifier with an additional UV light inside. It also comes with an activated carbon filter, so you have quite a few layers of protection and purifying in this. With these layers, there’s not only allergen protection, but germ and odor protection as well. It’s as simple as plugging in the air purifier to have it work.

This air purifier is for smaller rooms, being able to cover about 430 square feet. It’s great for the bathroom, office, or bedroom. It is completely safe and has LED indicator lights, along with a front panel touch button control system.

Ionizing Purifiers and Ozone Generators

The basic thing about ionizing air purifiers is that the machine uses high voltage to electrically charge air molecules. This eliminates the airborne bacteria and allergens and reduces static electricity build up in electronics. These ionizing air purifiers will draw the microbes from the air, walls, and ceiling similar to how static electricity draws things to it.

Ionizing purifiers are similar to ozone, but ionizers use electrostatically charged plates to charge gas ions and produce a bit of ozone themselves where ozone generators attract an extra oxygen ion. Ionic air purifiers seem somewhat complicated, but you can think of it as zapping all the allergens in the air and making them inactive.

There have been studies that ionizing purifiers and ozone generators are health hazards, however. They produce lung irritants and have been known to worsen asthma in people. They have been banned in the state of California, so in order to take your health into consideration, we will not be listing any on this page, but we have a page here that lists some guidelines and offers product recommendations. Hardly anything beats HEPA and carbon filters, so we suggest going with one of those if you don't have mold in your house.


While air purifiers can be expensive to cover an entire home, there are some smaller ones that you can have in your bedroom or office for maximum comfort. Even if you suffer from seasonal allergies, air purifiers can do wonders for your health. While most can get through life without needing any purification to your air, it can help a lot, even if you suffer from sniffles on occasion.

One air purifying machine can make your comfort increase in leaps and bounds. Even those without allergies may be affected by dust and odors. Air purifiers can help with any breathable air that you may come into contact with, like smoke from cigarettes. It’s a worthy purchase for anyone, so find your comfort zone today.
