Molekule reviews and complaints

Reviews and complaints for Molekule are a mixed bag. Consumer Reports tested the Molekule and offered a disappointing assessment, reporting a “Fair” rating while run at a high speed and a “Poor” rating at a low speed during a lab test involving particles — including dust, smog and cat allergens — that measured between 0.1 to 1.0 microns.

Molekule has responded to negative reviews claiming the testing standard doesn’t apply to its device, which uses proprietary PECO technology versus more traditional HEPA or CADR to capture extremely small particles, like mold. Though the National Advertising Review Board found that the Molekule addresses air pollution, it did not back up the company’s claims that the Molekule destroys all pollutants orr is superior over HEPA filters.

However, the company has performed tests through a third party that appear to reduce virus particles and mold. As far as what actual customers say, the Molekule earns a 3.5 out of 5 score on Trustpilot, with complaints about a buggy website and price not matching quality.

Positive reviews say the purifier helped with allergies and resulted in a noticeable change in their home’s air quality.

What sets Molekule apart?

Molekule reports that its products destroy viruses and pollutants that are 1,000 times smaller than what’s required of a standard air purifier. One of the company’s most attractive claims is the purifying process – it doesn’t just trap the pollutants in the machine, but breaks them down. Molekule notes that the light used to kill bacteria – UV-A – requires less energy than the typical UV-C light.

Another benefit is the low-noise feature. If you’re a light sleeper, you’ll appreciate the lack of constant whirring.

How can I contact customer support?

Reach out to customer service at 855-999-9069. You can also chat live with customer support through Molekule’s website or submit an online request.

Bottom line

If you have the budget, you might consider investing in a Molekule. But no worries if the price tag is too steep – you can find cheaper and potentially more suitable air purifier alternatives, some of which sell for less than $100.
