Cool lamp

I'm not sure if it is actually reducing co2 levels. According to my co2 monitor the levels have pretty much stayed the same as they were before but the lamp looks cool and it is fun to watch it turn green.

Worked well. Arrived alive and grew fast.

No more bloody nose

In the winter, even with a humidifier on my furnace I wake up with a bloody nose. I can tell when it is going to happen because my nose hurts. But, with the Algen Air, I have not had one! And, I proved it to myself because I was a couple days without it and immediately my nose hurt and was bleeding in the morning. The unit is not in my bedroom; it is in my home office so am surprised that far away can really make such a difference.

Great product

Great product

I had a 2.0 that unfortunately didn’t survive a move. Finally pulled the trigger on the 3.0 and am so glad I did! The new packaging is great, arrived with no issues and they do make a noticeable difference, especially in an urban area!

Love it!

When I saw my personal lab results and how much my Co2 levels had DROPPED, I knew the Aerium was working. The light is a little bright at night as we keep ours in the bedroom but I put something in front of it to block the brightness. We love it!

Easy to use kit, comes regularly

Works to bring down C02 levels. Comes a little too soon. What's with the X... Which isn't always present? Other ways to distinguish filter orientation?

Thank you for giving the aerium a try in your indoor ecosystem! We're glad you're happy with the performance.

Regarding the 'x' on the hydrophobic filter, we do our best to ensure that each filter leaves our facilities with a graphite marking to indicate which side is up. Another simple way to detect the filter orientation is to look for a waxy side (this goes down) and a rougher, paper-like side, which should have an 'x' (this goes down).

Additionally, you can customize the schedule for filter replacement anywhere from anywhere between 30, 45 or 60 days, depending on your growth period. We want to make sure the aerium works seamlessly for you. If you have any more questions or need further assistance, please feel free to reach out. We're here to help

Bubbly night light

We used a CO2 sensor to see what effect it had in the room. There was no statistically impact, though obviously some CO2 is being stored in the algae that grow.

Otherwise though, it's a pretty bubbly night light in our bathroom.

We did have the pump in the basement fail after about 2 months, but customer service was very prompt and helpful sending a replacement with no hassle.

Thank you for trying the aerium! We're very glad you are enjoying the aestetics of the aerium in your indoor ecosystem.

It's great that you have been monitoring the ambient CO2, we love hearing about the data that our customers collect! At this scale, the aerium does have its limitations, it's important to keep in mind that every indoor ecosystem is unique and performance may vary.

We're also happy that you had a good experience with customer service! We always looking to improve customer experience and device performance, so your review is extremely helpful.

So far so good!

Loving using protists/plants (i.e. nature’s solution) to improved O2/CO2 balance!

Aerium review

I actually love the product, it goes from a white color to a light green to a dark, it’s an awesome little nightlight, really quiet, I’ve had no issues so far, quite soothing at night when everything is shut down, I’d definitely say it’s one of the coolest modern day houseplants I’ve ever had.

Hello Joe,
Thank you very much for trying the aerium! We are glad you enjoy the modern houseplant in your indoor ecosystem. Please let us know how we can help in any way, and we look forward to continue supplying you with refill kits in the future!
Very Respectfully,

Happy Customer

Wonderful product.

The live spirulina is thriving in the highest quality glass container and acrylic unit — a work of brilliant biotech and luminous art. I'd share a 20-second video to show how beautiful this Aerium 3.0 really is, if there was an upload feature.

Love this air purifier but to keep it running its 300$ a year kinda steep

Something’s Off

Usually the refills are great but the last two have been off. They never really get very green and don’t seem to be making as much of a difference in the air quality as they usually do. I don’t know if the last batch of algae wasn’t very good or what happened but something has changed and not for the better.

Hi Amy,

Thank you very much for letting us know! My apologies if your recent refills have not been viable recently. We would be happy to replace your refill for free covered under your live algae guarantee, please feel free to reach out to and we will make it right!

Very Respectfully,

Great way to moderate CO2 in a home

I struggled with how to get rid of CO2 in the home. Opening windows certainly works but I don't want to do it during wild fires or winter months. Aerium 3.0, with additional light, helps a lot. (Reducing my CO2 by 100 ppm on average) I would definitely recommend this product.

Perfect for apartments

I live in an apartment where they’re doing lots of renovations. The fumes from that plus my own cooking results in less than ideal air quality. But the constant oxygen replenishment from my Aerium keeps the apartment air quality great!

Easy Peasy

25 plants in the house just like that. Easy to assemble and then watch it grow. No maintenance.
