How to choose the best mold air purifier

To avoid harmful mold spores issues the air purifier is the primary assistant. From one side it’s very simple to make the decision to purchase an air purifier to get rid mold spores for healthy reason. However, so many doubts and questions appear when it comes to the best device that kills mold. How to select the right model for the purpose?

Below there are major attributes or “must be” features for the mold air purifier to perform excellent work.

1. The purifying system has to be capable to release the air from mold spores

It’s essential the device should have several stages of cleaning for the reason that only cooperation of various technologies guarantees perfect results in mildew removal.

The chief in this process is the True HEPA filter as this technology is certified to capture up to 99.99% fine particles with their minimum size of 0.3 microns. Consequently, it’s exactly fitting system to catch the mold spores as they are usually sized 1-40 microns. More budget-friendly but less reliable are ordinary or like HEPA filters.

The filters with Activated Carbon are irreplaceable in musty odor absorption due to their ability perfectly manage with toxic microbial and volatile organic compounds which fungi secrete.

A useful supplement is an Antimicrobial filter. It not only finishes off the mold residues yet prevents the growth of harmful bacteria on HEPA filters assisting to save the efficiency of air purifier.

Targeting to break the DNA of fungi the Ultraviolet (UV) light is one more important fighter with mold spores.  Its crucial UV have to be designed with safety for people and pets.

This feature is an excellent supporter for HEPA filter to win the battle with mold spores in the air.

2. Appropriate power

The device should be strong enough to protect the required area and air volume so it’s one of the key criteria when buying air cleaner for mold. Always check the offered footage it can perform thoroughly. Accordingly, the purifier which is able to cover 400 square feet is suitable to eliminate mildew spores in the rooms below this figure. Placing the too powerful machine in smaller apartments will not bring faster and better results.


Clean air delivery rate (CADR) informs how fast the mold air purifier will do its job in a specific area. The higher this index is the faster mold and other unwanted things it removes.

Air changes per hour (ACH) indicate the frequency of the air rotation per hour. In other words, if the fan circulates the air over the filers more often the indoor atmosphere will be cleaner.

4. Price and maintenance cost

Of course, the cost of air purifier that removes mold matters is in the center yet aside from that there are hidden expenses that should be taken into account too.

So it’s worth to know the term of warrantee and quality conditions of technical support offered by the manufacturer. The other issue is the filters’ replacement charges that’s why it’s better to know in advance the availability of spare parts and how costly they are.

Keeping in mind the above information it is easier to avoid any disappointment after purchase.
