HELP—My Apartment Has Mold!

A call we receive a lot is from apartment renters who have problems with mold. They’ve told their superintendent that a mold problem exists, they’ve tried to remediate the mold themselves and they’ve even tried to break their lease. But often, apartment dwellers are stuck between superintendents who just don’t care and the fear that their health is at stake.

Many apartment dwellers complain of increased sinus infections, upper respiratory infections—even bronchitis, pneumonia and far worse. But still their pleas go unanswered. Their illnesses checked off as a figment of their imagination, or not the responsibility of the apartment owner. And the mold remains. And the situation worsens.

Can Air Purifiers REALLY Help?
Air purifiers are certainly a viable, affordable option for renters with mold problems, especially since many of them are looking for a temporary solution until they can have the problem resolved permanently, or find a new place to live. Either of which is advisable.

We’ve said it before and we’ll say it again—air purifiers cannot remove mold.

What air purifiers can do is filter the dangerous mold spores and mycotoxins that are produced as a byproduct of mold, and which can also make you sick. Very sick.

A Common Mistake
A common mistake that people make when purchasing an air purifier for mold is stopping at a HEPA-only air purifier. Indeed, HEPA filters play an integral role in the filtering of mold particles and spores, but as we will explore in the Recommendations below, they fall short of providing a complete solution.

Beware of Ozone Air Purifiers
Now before we get to the solution, I want to add (just in case some of you don’t make it to the end of this blog) a word about air purifiers that emit ozone to clean indoor air of pollutants, such as mold. According to the EPA, “whether in its pure form or mixed with other chemicals, ozone can be harmful to health.” Moreover, “if used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants.”

In a nutshell, ozone air purifiers can be dangerous, AND even if they weren’t, they don’t work anyway.

Recommendations
AllerAir recommends air purifiers that combine a HEPA filtration system, a deep bed of activated carbon and UV light technology.

1. HEPA
No question, HEPA is a key ingredient in the war against mold. The HEPA filter serves to trap 99.97% of the mold particles. However, something to keep in mind when dealing with mold. When choosing a HEPA filter, make sure that the lid (that holds the web of fibers together) is not made of cardboard, as this is an ideal food source for mold. A better choice would be a lid made of metal or polyurethane.

2. A Deep Bed of Activated Carbon
The activated carbon works to adsorb that musty smell that is associated with mold and adsorbs its harmful mycotoxin gases. The deeper the carbon filter, the better the adsorption capacity. An acceptable filter depth might be around 2”, but a better filter depth would measure closer to 3” or 3.5”.

Your carbon filter is important because it dictates the dwell time that a pollutant remains in the air purifier. The deeper the filter, the longer the dwell time. The longer the dwell time, the better the adsorption of the air pollutant.

3. UV Light
The UV light’s role is to sterilize any mold spores that are not trapped by the HEPA filter. This may seem irrelevant considering the HEPA traps 99.97% of the spores, but when it comes to mold, even the .03% that escape the HEPA filter can be enough to propagate a new mold problem. Plus, UV light technology also sterilizes bacteria and viruses, so if you’ve invested in a good air purification system, it just makes good sense to cover all your bases.

Why Invest in an Air Purifier if I’m Going to Eventually Leave My Mold-infested Apartment Anyway?
If today you rent a mold-infested apartment, then you need protection. The great thing about air purifiers, really, is that they serve many purposes. This means, when you move into your next home, you can use this same air purifier for general improved indoor air quality, or to remove Volatile Organic Chemicals (VOC’s) that are generated through new home furnishings and renovations. In fact, you can use your air purifier for a myriad of indoor air quality solutions—mold just happens to be one of the many great applications.

  1. I think the addition of UV is a good idea, as the use of ultraviolet (uvc) for not only air purification, but for water, and now even for blood (it improves the redox in patients) is becoming more widely used and accepted as a safe alternative to chemicals and many other methods that can pollute or have other harmful side effects.
