I live in an area where radon issues are common. A (nonsmoking!) friend died of lung cancer and radon was the probable cause. So it is something we should all take seriously. The building code here requires radon mitigation in all new houses, and mine is new enough to have it. But I wanted to check whether it is working, so I got this Ecosense EB1000 Ecoblu to test it. Set it up in my basement and the numbers are high, between 5 and 6! Yikes! I read the review from Brian B, who says it reads inaccurately high. So I tested this myself by moving the Ecoblu outside. I left it outside for four days and never saw it read above 0.3. Brought it back inside and it quickly shot back up over 5. Based on my comparison, outside to in, I do NOT think it reads inaccurately high. I think I have an issue here. My existing radon mitigation is a passive system, just a pipe from the sump crock out through the roof. The next step here is to add a fan. I have the radon mitigation people coming out to do that in a couple weeks. I will have them do a professional test as well, just to confirm these numbers. I will update this review to report how it turns out, but it’s going to take a while to find out. All my friends want to borrow it now. I am encouraging them to get their own! Edited Nov 17 2022: I promised to update this review to let folks know how this turned out. It took a couple weeks to get the radon mitigation company out here. During this time we saw numbers as high as 14 on our Ecoblu. Yikes! When the pros finally got here, they could not upgrade our system with a fan, due to how the pipe was routed. They wanted us to get someone else to come out and reroute the pipe, first. They also diagnosed another issue with our passive system. The radon pipe comes out of the sump, which is supposed to be otherwise sealed. But we also had several vented pipes going into that same sump crock, which were allowing radon to seep in. Ultimately, my husband did the fix himself. He rerouted the radon pipe, added the fan, and changed the other pipes to not vent through the sump. Within a few hours of these changes, our Ecoblu reading had dropped below 1 picocurie. It’s been several days now and it continues to hover between 0.5 and 0.9. I am so relieved!

This radon monitor could not be easier to use. Take it out of the box and plug it in. Once powered up, it reads the radon level every 10 minutes. Using the push-button on the back will cycle through the various reading averages with every push - real time, daily, weekly, monthly, and long term. Real time - updates every 10 minutes with the latest reading Daily - updates every hour with the last 24 hours of moving average Weekly - updates every 24 hours with the last 7 days of moving average Monthly - updates every 24 hours with the last 30 days of moving average Long term - updates every 24 hours with total days averaged since monitoring began In our case, the alarm went off within a few hours of plugging it in. The alarm defaults to alert when the radon level read is over 4 pCi/L (the EPA recommended level to mitigate), though you can adjust between 2 pCi/L to 5 pCi/L. Our readings range between 1 pCi/L to 10 pCi/L at various times and locations within the house so we are now looking to find a reputable and knowledgeable mitigator. To better diagnose our particular problem prior to paying someone to monitor, assess, and bid the job, I subsequently also purchased the EcoQube, which logs readings every 10 minutes. Their smartphone app allows viewing the logged readings as well as viewing averages by day, week, month, and year. Additionally you can export the data for your own data manipulation. I find this to be better suited for diagnosis purposes since I can place it any room for 24 hours and see the graph of every reading over a 24 hour period (or more). The EcoBlu is fine on its own for long term monitoring either if you don't have a radon problem, or after mitigation when you want to monitor the efficacy of your mitigation system. I prefer the EcoQube for diagnostics efforts with its ability to offer a finer granularity to the readings and downgraded the EchoBlu 1 star for that reason.

When we bought our house 3 years ago, a radon test was required. The level came back at 8pCi/L, so a mitigation system was installed. It pains me to think about the previous family that lived here for almost 20 years and having no idea what the radon level might have been and knowing how easy it would be to assume it will remain low. This product is pricey, you could do a yearly mail-in test for 10 years for this price. And it doesn't have wifi or an app like some other products in this price range. I don't care so much about that, but other people might, and this does collect lots of data that could have been useful to view in another manner. This is mostly why I'm taking off the one star. However, this feels like a quality product. It looks and is packaged like a nice consumer electronic, not any kind of industrial equipment, and comes with everything you need to use it including a power block. You could easily display this anywhere and it looks like a cute little clock. It could not have been easier to use - open the box, plug it in, and you start getting real time readings shortly after. The instructions say to place it 20" from the floor or any walls. The floor is easy, any counter or shelf works, but 20" from the wall may not always be possible - not sure how that affects readings, but we'll see as I move it around the house. There's only two buttons, one to change the readout (real time, various averages) and one to change settings (brightness, units). I'm a little torn on not having an app to view the data, but I do love the simplicity of not having to set anything up or having to download anything. The only other hesitation I have about this is that I'm not sure how you'd confirm that it is or remains accurate. The instructions I think say the accuracy is +/-0.7 pCi/L, which may be fine generally but seems a little large when the safe level is 2.

After a family member decided to do a radon test and found they had higher than recommended levels, I thought it would be a good idea to test our home. Radon is an odorless, colorless gas which can seep from the ground into your house and you'd never know it was there. But, it reportedly is the second leading cause of cancer. So, it's worthwhile to check and not crazy money to fix. This unit couldn't be more simple to operate. Unbox it, plug in the included USB-C cord to the detector unit and the included adapter, plug that into a standard outlet, and then wait for the number. First reading is in 10 minutes but I found the reading went up for about an hour then seemed to stabilize. At the end of the first day it was around 4.0, the following day about 3.75. General suggestions are to fix anything over 4.0 and consider fixing anything between 2.0 and 4.0. But, Radon can go up and down so next step will be to use the weekly average function, which should give a more meaningful reading. Most local health departments can provide advice on how to do a reading using a kit and sending it to a certified lab if you desire a "second opinion." But, this detector gives you a good starting place, or can be your final word if you wish. Your health department can also likely recommend a good company to mitigate your radon levels, which usually involves a combination of sealing and ventilation. If you are worried about it in the mean time, you can usually reduce radon levels by cracking open windows to provide fresh air and increase ventilation. One of the additional benefits of having your own meter vs. just doing a one-time test kit, if you open windows or pay for a company to do mitigation, your meter will verify the effectiveness of either method. Good detector. Five Stars.

When I originally got the device, I thought I was getting a battery powered one. Since then, the vendor made it clear in the product description that it is not. Aside from the cube-shaped monitor, the product comes with a stand and a USB-C cable and 110v power adapter. Setup was a breeze: just take the items out of the box, clip the stand onto the cube, and plug the device in. Less than 60 seconds. In just a few minutes, I got my first Radon reading. Nice! But because it's not battery operated, it's hard to find a good place for this Radon monitor. While this white cube isn't offensive looking, the black cable does look ugly when the device sits on a book case or coffee table. And those furniture items have to be near a power outlet. And the user guide says the monitor must be at least 20" from a wall and 20" off the ground. Not easy to fulfill all those requirements - and nearly impossible to hide that ugly cable! I asked the vendor about the silliness of not having this be powered by batteries - as are my VOC monitor and my temp/humidity monitor. The vendor said that accurate and frequent monitoring would take too much power, so they had to decide on accuracy vs. portability. Not sure why Radon monitoring would take more power than VOC monitoring - and my VOC monitor also needs to send its data via wifi to my HomeKit app, whereas this monitor doesn't even have wifi. Anyway, if you have agood place to put this monitor, I highly recommend it. If you're like me and don't like ugly cables staring in your face - especially for something you only occasionally look at - you might be better off looking for a wireless radon monitor. I deducted one star for it not being wireless because that's what I thought I was getting.

Its lightweight and as small, comparable to a teabox. You don't have to do anything much, just setup the legs and plug it in. It takes about 10 min to see the first reading. The reading does vary by hour and even by location. The closer I set it to my basement level, the higher the level I saw. When it hits a level of 4.0, it will beep for a little bit and show a red line over the number. It will not continously beep because thst would just be annoying. Thank goodness. I don't place it near moving air such as outside walls, vents, or windows. I set it on a table 2ft off the ground and near the indoor wall. It's also recommended you keep this away from. Electromagnetic frequency emitting devices such as your wifi router, or microwave to name a few. The device just let's us know when we need to crack a window open to preven hitting anything higher than a 4.0. Since we got the device, we have just implemented a habit of cracking a window open in the afternoon on the side of the house facing the sun. We open the window on the lowest level since radon sinks the the ground. Thankfully our garage is on the same level, so occasionally I will leave the garage open with fan running on the floor to speed things up. What's great is that you do see the number go down on the device after 30 min to an hour. There was a time it just kept going up even with the garage open. I can only assume the levels would have rose higher had I not had the garage open. Winter is coming so this will be definitely be handy in keeping us safe and help us determine if we need a mitigation system in place.

This radon detector and monitor seems to be working for us here in Arizona. We have the monitor at the recommended height in our hallway just outside our three bedrooms. It's summer now and the real-time measurement fluctuates through the day from .5 to 1.7 spikes a couple times. I believe that is okay from what I have gathered so far about the radon gas released from uranium within Earth. I'm still trying to learn how to understand the measurements and used a normal levels guide from an Arizona Geological website. It's still over 100° here and we cannot open our windows until October evenings. Personally I would prefer no radon gas and it makes me uneasy because I can't smell it or taste it to avoid it like I can with other dangerous vapors. This is why I like having the monitor and it helps ease my thoughts a little bit since the readings are 'normal' levels. I am anxious for the cooler weather and more ventilation so I can see the lower radon levels from the monitor readings. I hope they're lower because the readings over 1.0 right now start to make me think I should possibly invest in some radon mitigation methods 5 stars from me. Hope this helps. Thanks.

First, the refresh rate of the LCD seems to make the picture flicker, but in person it looks great. I just wanted to show that yes I am using this. If you are looking at this you probably either want to monitor your radon levels because you have a problem, or you have a mitigation system that you want to make sure continues to work properly. This is great for that. It adds peace of mind to know that things are ok, or it shows you if there is a problem. It is not a connected device so it won't send you alerts etc, but radon is one of those things I only care about if we are in the area so that was fine with me. I also hate how everything is connected these days sending data to a cloud somewhere, so again I like that about this device. I'm looking forward to watching this over time so I can see how it drifts with our habits (windows open vs closed etc). It will also be nice to know if there is an issue so we can work on mitigation if needed.

When I first moved in my house, I had a company perform a radon test during inspection, typically these tests are performed in the garage or lower section of the house because it's where the radon levels are the higher, but I always wondered if the day by day level in the house were safe. Now I can easily keep track of radon level, in my living space, both real time or with a daily, weekly, monthly, and yearly average. It seems to be fairly accurate, since the level changes every time I ventilate the space. Several times the level was over 2pCi/L, which is the first threshold for safety. The levels fluctuate daily and are easily influenced by the wheatear/atmospheric pressure, but I can easily keep track of everything with this detector and eventually decide if I need to install any mitigation system. This could really turn out to be a life saver! Don’t think twice and buy it, it’s well worth yours and your family’s safety!

This was unbelievably accurate. My house was tested for Radon a month ago with a reading of 2.01 by a lab- this device registers 2.0 to 1.97 to 1.67 throughout the day, so it's very close to the lab tested amount. The plastic feels a bit on the flimsy side, but shouldn't matter too much since it'll just sit on a table or shelf. I'm withholding a star for the fact that this can't be connected to anything smart - no integration. So you have to go in person to see the reading. I have it in the far part of my basement. Would've been great if it had some sort of integration to Home Assistant, or SmartThings or even a simple web ui. I guess that adds a lot of complexity to a simple device, so it wasn't an option. The accuracy earns this all it's stars. Bonus is that it's USB-C, not micro-usb... AND it comes with plug and cable.

I have professional background using many types of test equipment & detectors. After giving this a long test run since Radon is a daily fluctuating occurrence. This makes it very hard to assess this detector's accuracy. It has different settings & functions for quick response, long-term, etc. It also has an easy-to-read display. This tester sits on a little stand as a clock would. I've seen it jump readings from very low to higher in a very short span of time. We have had our home tested by professionals & results were very low radon. I also have mixed feelings on Radon's effects since it has been so commercialized for $$$$s I'm just not sure if it is even the health threat it's made out to be since it has been around for most likely forever.

Got this to do monitoring in an older home. It's very easy to use, just plug it in and it starts working. I don't know yet how accurate it is. I've just sent off a conventional short term test to the lab so we'll see how the results compare to what this detector is reporting. Pros: Very easy to setup and use Clear instructions Cons: None yet. If I needed another detector to have in another location I would buy another one, assuming that the accuracy is confirmed by lab test results of a conventional short term Radon test kit. But in reality it is easy to move this to different locations in the home for testing, so other than for convenience you probably don't need more than one of these detectors.

I have used other types of radon tests in the past, including the mail in devices, but the accuracy of this electronic model, and the ease of use can't be beat! It's literally as simple as plugging it in with the included power cable, and just leave it alone. Gives a reading as fast as 10 minutes, and then it gets more accurate the longer you leave it in place! I LOVE this thing, and there's no waiting for extended periods of time and then waiting to mail off units for measurement by labs...none of that hassle! This is a great item for providing your family with peace of mind for your safety from radon! Highly recommended!

This is my second radon monitor. I set it up next to my other one to gauge accuracy and it stayed within .2 pCi/L, so it seems accurate. I really like the large display. I no longer need to walk across the room to check the radon level, just a quick glance. The one key missing feature compared to the more expensive units is the ability to download the data to an app and display a graph. You'll need to decide for your self if it's worth the additional cost. Personally, since this unit can display the average over a day, week and month, that's good enough and makes this unit a good value.

My son recently bought a house and had a radon removal system installed. While I don’t even remember our house being tested for radon for decades. I did my research and picked the most easier device out there, I’m not too good with technology. Indeed, its the easiest radon detector ever, the only thing I had to think about is where to plug it in. Other than that, the display is big and numbers are easy to read. I keep our reading on “weekly average” and curious to see the “monthly”. Definitely recommend it, - you’ll have peace of mind, cause no radon in your home.
