Air Purifiers Buyer’s Guide

Generally speaking, most air purifiers will remove the harmful allergens that come from mold and mildew spores.

However, not all air purifiers are the same. Get to know air purifier features so that you know which ones you would like to have.

Cleaning and Maintenance

All air purifiers work with a filtration system, so you need to replace the filters every so often.

Every filter has a specific life span that will be on the product descriptions. The typical lifespan for the HEPA filter and carbon filter is generally around three months, but some companies may last longer.

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 whenever you dust your home or at least when you replace the filters. That way, the air won’t be recontaminated by the dust collection.

Coverage Area

Each air purifier has a specific coverage area.

Some purifiers can cover much larger spaces than others, so check the specifications before you buy one of these devices.

Smaller rooms like bedrooms or bathrooms don’t have much square footage. You can get by with a purifier with a smaller coverage area. However, big living rooms and large basements will need an air purifier that is strong enough for that space.

Placing an air purifier in a room bigger than the coverage area will result in poor performance.

If you plan to use your air purifier in different rooms, opt for a device that covers up to about 500 square feet. Note that air purifiers with larger areas will need more power consumption.

Large, industrial-style machines can cover about 1,000 feet. They are more expensive, but you might want one of these if you have a larger home and want to avoid moving the purifier or buying multiples.

Fan Speed

Pick an air purifier that comes with at least three or four fan speeds. These units can adjust depending on what speed you need.

During the cold, wet months of the year, most homes become more prone to mold and mildew. You’ll want to amp up the fan speed during these months to avoid issues and remove impurities from the air.

During the hotter, drier months, low, energy-efficient speeds will save you money and still work to remove any allergens.

Filters

Air purifiers rely on the filters to clean the air.

Choose an air purifier with at least a two-filter system: a HEPA filter, and an activated carbon filter.

• Activated carbon filters: Activated carbon filters are responsible for removing the bad odors from the air. Mold and mildew give off a musty smell that is hard to remove. The activated carbon filters get rid of the stench.
• True HEPA filter: A true HEPA allergen remover is the only way the unit can remove microscopic particles from the air. These filters capture mold spores as small as 0.3 microns. Don’t get a purifier that says HEPA-grade or HEPA-style. Those don’t work as well as true HEPA filters.

With these filters, your air purifier will remove both mold spores and nasty odors from the room. They can also help if you have a pet allergy.

Noise Levels

Like with a dehumidifier or a tower fan, you need to get a machine with a quiet motor.

If you plan to use the unit in your bedroom or a living room, you need an air purifier that won’t wake you up or get in the way of conversations.

Check out the user reviews on websites like Amazon to see what people’s experiences are with noise levels.

UV Light

UV lights are controversial, but they’re a common air purifier feature for a reason.

The UV lights eliminate the microbial germs and viruses 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. Ozone is harmful, and having it in the home isn’t ideal for many reasons.

While many companies claim their units do not omit this harmful substance, some still opt to steer clear of it.

Do your research before committing to a purifier with UV lamps.

Some of our top picks for air purifiers have Plasma Wave technology instead of UV, which doesn’t give off ozone.

Warranty

Check the warranty time on your air purifier. 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. Some even offer a lifetime warranty.

What Is Mold?

Most people may not know that mold spores can be anywhere.

Mold is lots of small organisms. It comes in several colors like black, white, orange, green, and purple. Mold does well in moist, damp places with poor ventilation.

The mold in your home releases spores in the air, which you inhale. Inhaling mold has many adverse effects on the body.

There are two main types of molds that affect your body:

• Allergenic: Allergenic mold 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 can cause human infections. These are dangerous when ingested into the human body.

3 Ways Mold Can Affect Your Health

Exposure to mold isn’t healthy. The extent of how bad it is depends on the person and their health history.

If a person has a mold allergy or a lung disease, 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 at risk when exposed to mold are young children and elderly people. Their immune systems are much weaker.

However, mold can affect healthy adults as bad too. Here are three problems mold can cause.

1. Allergic Reactions

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, inspect for mold.

If your home has humid rooms, increase the ventilation and air quality with a dehumidifier and an air purifier.

2. Weakened Immune System

If you or someone in your family suffers from an immune system disease, avoid mold spores at all costs.

Prolonged exposure to mold spores causes the immune system to worsen. It can also cause lung infections.

Even if you aren’t suffering from an immune system disease, your immune system will weaken over time after continuous exposure. Young children and elderly people are most likely to have their immune systems weaken.

3. Cancer and Other Long-Term Effects

Cancer may seem like an extreme health effect, but long-term exposure has connections to serious health issues.

The risk of getting cancer or cardiac or pulmonary diseases multiplies when dealing with children or older people.

Tackle mold head-on when you first see it. Get an air purifier to improve the air quality.

How a Purifier Gets Rid of Mold

How does an air purifier get rid of mold?

The truth is, if you have a mold infestation, you will need more than an air purifier.

Purifiers get rid of the mold spores that are in the air. You will need to remove the mold on the surface or get a professional to do it for you.

Air purifiers pull in the gross mold spores and other germs in the air through the HEPA and active carbon filters. The air purifier then releases the clean, dry air back into the atmosphere.

Air purifiers are excellent for mold prevention or to clean the air after a mold infestation.
