Best Air Purifier Buying Guide

While filter type is one of the most important features to consider when choosing an air purifier for mold, there are several other key features as well, which you need to remember.

  • Coverage Area

The coverage area can be simply defined as the amount of area that your air purifier is capable of cleaning without being overloaded. If you’re looking to save money, then it’s advisable to consider the area size for the unit you plan on purchasing. This is because the higher the coverage area, the more expensive the unit will be.

However, if money is not an issue, then it’s better to purchase a purifier which covers more area than you need. This will ensure that the purifier you choose will be able to clean the space effectively.

  • Filtration System

As mentioned above, the effectiveness of an air purifier is determined by its filter. That is why it’s essential that you choose a purifier with a certified HEPA filter.

Typically, units have several other levels of filtration as well. These include filters which only capture dust and filters which remove air pollutants as small as 0.3 microns.

As you are trying to remove mold spores, it’s important that you choose a purifier with a filter specifically designed to capture even the smallest particles.

  • UV Lamp

Besides the filtration system, a UV light is another key feature you need to consider before purchasing a purifier. Due to their effectiveness at removing mold and bacteria, they are sometimes also used as water purifiers.

The UV light has a simple operation. Once the airborne particles are captured in the purifier, the light shines on them as they are trapped by the filter. The UV light then neutralizes and kills almost all allergens, mold spores, and bacteria which it comes in contact with.

  • Noise Level

It is advisable to choose a purifier with a relatively quiet fan. This will ensure that the unit has a quiet operation, allowing you to get a good night’s sleep without waking up. It will also make your house a much more peaceful and quiet place.

  • Speeds

Choosing an air purifier with different speeds allows you to run the unit at faster speeds if required. For example, if you have a prevalent mold issue, a faster speed enables you to tackle the issue instantly. You will not need to wait for a slow purifier to start working.

But there’s a catch. The faster your unit is working, the more noise it is going to make. If you’re planning on using a purifier near you, then it’s advisable to choose one which can run at a slower speed when you’re present, and at a faster speed when you leave. As a result, you won’t have to deal with any unnecessary noise.

  • Power Consumption

Let’s face it; if you’re planning on purchasing a purifier to remove mold, it’s going to be running almost constantly. Thus, it is essential that you choose an energy-efficient model. It is advisable to purchase one which has an Energy Star rating, so it runs as economically as possible.

  • Air Quality Indicator

One of the worst things perhaps you can do while using an air purifier is assuming that it’s running efficiently all the time, particularly in a moldy situation. Hence, you should purchase a model with an air quality indicator.

This indicator will inform you if the air needs less or more intensive filtration. It will also conserve energy, even on the highest speed and won’t underperform if mold or mold spores are present.

  • Warranty

If you’re trying to remove or prevent mold, then your purifier will have to work efficiently and continuously. Thus, it is essential that you choose a model which comes with a good warranty.

As a result, you’ll be covered if any of the parts break down or fail you. Otherwise, you’ll have to get a costly repair to get your purifier working again.

Mold Health Effects

Once humans are exposed to damp environments, they can start developing several different health issues, depending on their sensitivity. However, some people are highly susceptible and sensitive to mold. As a result, they suffer from nasal stuffiness, wheezing, coughing, irritation of the eyes, throat, and even on the skin when they come in contact with it.

Some individuals also suffer from mold allergies, which cause more severe reactions.

Individuals who already suffer from chronic lung illnesses or a damaged immune system can get severe lung infections once they are exposed to mold.

Hence, they should avoid areas which can get mold at all costs. Such spots include wooded areas and cut grass as well. If any individual from your family suffers from such a disease, then it is advisable to get a whole house air purifier.

Furthermore, several studies throughout the years have discovered a link between upper respiratory tract symptoms and indoor mold. These symptoms include asthma, coughs, and more.

Other recent studies have also suggested a link between the development of asthma in some children and early mold exposure. This is particularly for children who might be at a higher risk of asthma.

Some recent studies state that selected interventions and improved housing conditions can reduce the risk of respiratory allergies and asthma. However, more research is required in this regard.

How To Test For Mold In The Air?

One of the most popular ways to test for mold in the air is to use viable mold test kits. You can easily purchase these from online retailers and home improvement stores.

However, the tests vary from one kit to another, and it is essential that you know the difference. This is because some kits are designed to only test for the mold found on surfaces. Hence, if you want to see if it’s present in the air around you, you must know how to check the quality of the air you breathe.

There are several spots where mold can easily grow undetected. Thus, some smart locations to test for mold include:

  • Underneath stacks of cardboard and newspapers
  • Behind the refrigerator
  • Below sinks
  • Behind wall stud areas which contain plumbing lines
  • Under carpeting which was wet at one time due to carpet cleaning or flooding
  • Inside ventilation ducts
  • Backside of acoustic ceiling tiles
  • Behind the wallboard near leaking windows

The entire testing process can take a few days. If the result is positive and you do have mold spores in the air, then it’s advisable to send the test materials to a lab. A further examination will then be conducted to determine the type of mold present in your house.

Do Air Purifiers Work For Viruses?

If your house is already contaminated with microscopic viruses, they will keep re-circulating throughout the home. This is because your house is tightly closed and safe, and the viruses have no way to escape. As a result, you’ll breathe in the contaminated air and might become highly susceptible to a cold or flu.

But don’t worry! By installing an air purifier, you can capture these particles and eliminate the viruses. The best models which are designed to stop the spread of viruses are those which feature a true HEPA filter.

Moreover, if the unit features a UV-C light filter or an ionizer, it will be more effective against viruses. The proper use of air purifiers ensures a higher quality of improved air. With an effective model, the air around you can become healthier and safer to breathe.

However, it is essential that you adopt other sanitary and hygiene habits to further prevent the spread of viruses. Covering coughs and sneezes with a tissue, regular hand-washing, and wearing a hospital mask in public are some of the most effective and recommended habits.

Do Air Purifiers Work For Allergies?

Air purifiers are powerful machines which are capable of filtering out particles as small as 0.3 microns from the air. But how does this help your allergies? Because air purifiers are able to capture all potential airborne allergens, they can completely help you with your allergies.

Along with improving the air quality in your house, air purifiers also keep you healthy if you’re suffering from extreme allergies. But there’s a catch. These units can only trap airborne allergens.

As mentioned above, they are able to capture 99.97% of airborne allergens, including pet hair, mold spores, pet dander, fungus, dust, dust mites, and many other types of bacteria. Furthermore, these units circulate the air in your house, changing the fresh air several times.

Air purifiers come with air filters, which help trap the tiniest airborne allergens. Some of the most common filters used to eliminate the sources of allergies include:

  • Ionic filter
  • HEPA filter
  • UV-C light filter
  • Activated carbon filter

Choosing the right air purifier can help eliminate airborne allergens from your home. These units can also help remove odors, which irritate your respiratory tracts and make you sneeze.
