Air Purifiers Buyer’s Guide

Generally speaking, most air purifiers will remove the harmful allergens that come from mold and mildew spores. However, there are several features you should look out for when looking for an air purifier.

Filters

Air purifiers rely heavily on the filters to properly clean the air. A good rule of thumb is choosing one with at least two filter system, and always with a HEPA filter and an activated carbon filter. With both of these, you can be assured that your air purifier is removing both mold spores and the nasty odors from the room.

  • True HEPA Filter– You’ll see all air purifiers with True HEPA filters listed on their product description sites, but what does this mean? A HEPA filter is the only way the unit can properly remove microscopic particles from the air. They capture mold spores that are as small as 0.3 microns from the air. Be cautious when shopping for an air purifier some of them will say HEPA-grade or HEPA-style, which isn’t actually true HEPA. We recommend the latter.
  • Activated Carbon Filters- Activated carbon filters are the ones responsible for removing the bad odors from the air in your home. Mold and mildew give off a musty smell that is easy to note and hard to get rid of. The best air purifier for mold will also have the activated carbon filter to get rid of the gross stench.

UV Light

Before we get into the controversy surrounding the UV lights, we’ll explain exactly why many air purifiers are made with this feature. The UV lights are there to eliminate the microbial germs and viruses that are in the air. You may see UV-C lights or UVGI (Ultraviolet Germicidal Irradiation) listed on the product description.

The reason why this type of light is controversial is because of the production of ozone and radiation that these lights give off. Ozone is extremely harmful and having it in the home isn’t good for many reasons. While many companies claim their units do not omit this harmful substance, some still opt to steer clear of it.

As always, do your research before committing to a purifier with UV lamps. Some of our choices for best air purifiers have Plasma Wave technology instead of UV, which doesn’t give off ozone said to be much better for the home.

Fan Speed

Pick an air purifier that comes with at least 3 or 4 different fan speeds. These units are preferable because of the ability to adjust depending on what speed you need. Generally speaking, during the cold, wet months of the year homes become more mold and mildew prone. You’ll want to amp up the fan speed during these months so you can avoid any issues and remove any impurities from the air.

During the hotter, drier months then a lower speed, which is also energy efficient, will save you money and still work to remove any allergens that may be circulating in your home.

Noise Levels

Just like with a dehumidifier or a tower fan, the noise levels are crucial when shopping for the perfect air purifier. The quieter machines are less detectable and won’t disturb as much as the louder machines do. If you plan to use the unit in your bedroom then investing in one that won’t wake you up is a safe bet. You can check out the individual user reviews to see what people’s experiences are with noise levels.

Coverage Area

Each air purifier is made with a specific amount of coverage area. Some purifiers have a span of a lot more than others, so it is important to check the coverage area before buying. For smaller rooms like bedrooms or bathrooms, you won’t need that much square footage, but for big living rooms and large basements opt for more square footage.

If you plan to use your air purifier in various rooms, a good rule of thumb is to opt for one that covers more area, up to about 500 square feet. There are always large, industrial-style machines available that cover about 1,000 feet as well, they just tend to be a bit pricier. Placing an air purifier in a room bigger than the coverage area will result in poor performance.

Cleaning and Maintenance

All air purifiers work with a filtration system, so they will need to be replaced every so often. Every filter has a specific life span that will be listed on the product descriptions. The normal lifespan for the HEPA filter and carbon filter is generally around 3 months, though some companies may last longer.

It is imperative to clean and replace the filters within the allotted time. Forgetting to clean or replace them will mean the machine isn’t working properly, and you run the risk of damaging it. Another great rule of thumb is to dust the vents as well so that the air isn’t being recontaminated by the dust collection.

Warranty

Make sure you check the warranty time on your air purifier. You want to be sure that if there are any issues, the company will replace or repair it with no additional cost to you. You can expect at least one year of warranty with most air purifiers, but some manufacturers offer more.

What is a Mold?

Most people may not know that mold spores can be found literally anywhere. The fungus is made up of small organisms and comes in several different colors like black, white, orange and green or purple. Mold does well in moist, damp places with poor ventilation. So in your home, if it catches on to a surface that has high moisture, this causes it to grow.

The mold in your home causes releases spores in the air which you easily inhale. Mold has many adverse effects on the body, but there are two different main types when talking about the air you breathe.

  • Allergenic– Allergenic mold refers to the type of mold that causes an allergic reaction when inhaled, usually in the form of normal allergy symptoms. These symptoms include coughing, itchy throat, watery eyes, and stuffy or runny nose.
  • Pathogenic– Pathogenic molds are the ones that can cause human infections. These are usually the ones you need to watch out for, as they are dangerous when ingested into the human body.

3 Ways Mold Can Affect Your Health

Exposure to mold obviously affects your health adversely. The extent of how bad it is depends on the person and their health history. If a person has a particular mold allergy or a lung disease then some of the symptoms will hit them differently. They may suffer stronger effects compared to someone who doesn’t have these health issues.

Other groups that are very at-risk when exposed to mold are young children and elderly people. Their immune systems are much weaker so they should avoid mold-susceptible areas. Either way, mold can affect healthy adults just as bad as anyone else. Here are some of the many consequences of being exposed to mold.

Allergic reaction

Exposure to allergenic mold can cause you to experience the normal range of allergy symptoms. If you find yourself sneezing, coughing, tearing up or with a tight chest when at home then inspect for mold. Homes with humid rooms should invest in proper ventilation with a dehumidifier and an air purifier.

Immune System

If you or someone in your family suffers from an immune system disease then you should avoid mold spores at all costs. Prolonged exposure to mold spores will cause the immune system to worsen and could cause infections in the lungs.
Even if you aren’t suffering from an immune system disease, your immune system will weaken over time after continuous exposure. As mentioned above, this is extremely true for young children and elderly people.

Cancer and Other Long-term Effects

Cancer may seem like an extreme health effect but long term exposure has been proven to be linked to serious health issues. The risk of getting cancer and/or cardiac or pulmonary diseases multiplies when dealing with children or elderly people. It is always best to tackled mold head on when you first see it and get an air purifier to improve the air quality.
