Adya® Products Reduce More Than 99% of Microcystin-LR (Toxic Algae)

Since the Toledo water crisis occurred, many people have wondered if any home filter systems exist that could have protected against the toxin that contaminated tap water to over 400,000 people. Experts have agreed on one answer, no. This is based on the fact that no filter systems have been tested for the removal of this toxin. A recent article published in the Toledo Blade said this:

“Even though filter manufacturers can’t guarantee their systems will filter out the Lake Erie toxins, that doesn't mean that they won’t. It just means that they haven’t done sufficient testing for the toxins. The manufacturers now say that they are looking at testing their equipment for microcystin toxins.”

And that’s exactly what we did. The Adya Clarity Water Purification Solution and Adya Water Filtration System* were sent to GreenWater Laboratories, a leader in cyanotoxin analysis and the identification of algae/cyanobacteria, to test for the removal of Microcystin-LR. One liter of water was spiked with 10 ppb of Microcystin-LR, nearly four times the amount that was found in Toledo’s water supply. Adya Clarity was added to the spiked water and poured through the filter system. Below is a summary of the results. 

Summary of Results

MC Levels (µg/L)
Pre Filtration (10 ppb MC-LR)
Post Filtration (10 ppb MC-LR)

ND = Not detected above LOD/LOQ   |  LOD/LOQ = 0.15 µg/L

The results indicate that after filtration, Microcystin-LR was non-detectable in the water. This proves that our products can be used by consumers to effectively protect their drinking water from Microcystin-LR contamination, as well as a remediation for other freshwater sources. It is our goal to partner with companies and organizations that are working to eliminate harmful algae blooms that threaten our water supplies, especially the Great Lakes.

What is Microcystin-LR?

Microcystin-LR is one of many toxins produced by cyanobacteria, also known as blue-green (toxic) algae. It is the most frequent and most toxic form of microcystin, and the specific toxin that contaminated Toledo’s water supply.
