    Glad to here from you again.
    Do you consider fresh air change and maintaining humidity levels to be part of good indoor air quality?
    If so how much air change and what humidity level.
    Keep us posted.

    Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"

    Here's the carbon filter- https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
    Here's the matching inline fan - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

    It's loud, not pretty and aimed at the marajuana growers market -But it's very impressive in reducing VOC levels measured with an industrial PID meter.
    My go to device used to be the Austin Air HP+, but this device offers significantly better results at about 1/3 the cost.

    Here's the link to the Austin Air device I was using previously.
    Probably a safer bet than the other device as regards warranty and an established company:
    https://austinair.com/shop/healthmate-plus/

    A Canadian company, Airpura, also makes reputable devices.
    The TeraBloom units I referenced though had significantly better VOC reduction numbers than the Austin, but it's ugly, loud and I don't know how long the carbon will take to saturate.

    I have tried both units, and many others over the years.

    I suffer from a respiratory disorder called chronic bronchitis
    and Bronchiectasis, a condition in which the lungs fail to remove
    mucus within the lungs in a normal way.

    I will state sincerely and in good faith that the Molekule profoundly
    helped assuage the sequela of my symptoms, versus the many other
    air purifiers I have tried...and profoundly

    I was reading today where at ClinicalTrials.gov that a investigation
    is underway to evaluate the efficacy of the Molekule in ICU
    hospital rooms.

    I certainly don't deny your report. Lots of folks have have posted similar results(on the web) and I'm certain many are sincere.

    My report is very specific - Lack of VOC reduction measured with a industrial grade PID meter whereas heavy carbon devices showed large reductions in the same test setup.

    VOCs are just One aspect of IAQ and probably not the most significant for the sorts of problems you and most other folks buy an air purifier. In fact the developer designed the product because of his son's server allergy. Particulates, another component of IAQ, are generally involved in respiratory/allergy aliments. The MoleKule might work great for that. I do not know, it's not what I tested for.

    I bought the device because is was promoted, among other things, to reduce VOC levels. I was also impressed with the science expertise of the developer and head scientist. I'm still impressed with these guys. Also MoleKule's 3rd party lab testing is significant. Problem is these results haven't been shown to translate to real living spaces - homes. All test result are in small non real world stainless steel enclosures with contrived setups. I'm suspicious because all MoleKule, RGF and any of the PCO manufacturers need to do is run simple inexpensive tests in real homes. Instead they spend lots of money testing in big fish bowls with very untypical mixtures of VOCs. This criticism is not limited to MoleKule but all the major players(RGF). VOC reduction in homes is very easy to demonstrate . If these device work like we want them to work - homes- why don't the manufacturers present the data.

    Interesting conversion here. What you guys don't realize is the Molekule is about 15 years behind in PCO technology. We moved out of the prototype stage 12 years ago. Our system is for the most part commercial and light industrial. It can be found all over the world in Hospitals, Airports, Federal Buildings and more. The residential market is something we looked at in the beginning and decided against developing a product for it. I met Goswami at the Orlando AHRAE show over ten years ago. We had sent a prototype unit in for Energy Star Certification and he was in charge of the program at South Florida University at the time. Blew his mind the direction we were going with it. He maybe a great scientist but he doesn't know the HVAC industry. I have one of his table top units setting in our lab as we speak. And have ran it thru tests. They are miles away from having a commercially viable system for the HVAC industry is all I can say. The table top unit is a sexy looking unit built for a particular market group.
    The premise of ventilation is that the OA is clean or of sufficient quality to be used for dilution. Traditional ventilation is somewhat being threatened by the fact that the EPA is changing the requirements for outdoor air quality which is creating non-attainment zones in what is now becoming a significant portion of the country. That means that buildings in those areas will need to clean up the OA before they bring it into the building.

    Your comments are not surprising. We have seen this drill before - attractive design, questionable technology, insufficient testing results, and overblown claims. You are much more knowledgeable on PCO than I am, but I do know that one air change per hour in a typical sized room is a product killer for me. Even if it works as advertised, it is not powerful enough to overcome the activity in the space where it is being used to produce meaningful results. No wonder that the research finding that the Austin Air more efficient than the Molekule was the "genesis" of this thread.

    This is not a post. It is an advertisement - and a bad one at that.

    Thank you for removing the fake "testimonial" post.

    Meanwhile the National Advertising Division (NAD) of the BBB has recommended that Molekule discontinue it's pollution elimination claims and any claims of asthma and allergy symptom relief. It was found that these claims were unsubstantiated by evidence supplied by Molekule. It was also found that the claims concerning the superiority of the PECO technology over HEPA technology were not supported by valid research. Finally, the limited air cleaning capacity of the Molecule could not produce the results claimed in the Molekule advertisements. The full press release gives more details https://asrcreviews.org/nad-recommen...tain-findings/
