Do you have a budget to stick with? I’d look at something like an Alen breatheright flex in each room. They have a voc filter option that has extra carbon in it. However, Being that it’s a medical building is there already some kind of air exchange that could be adjusted? Have you talked with your facilities person? I may start there before going the purifier route.
r/AirPurifiers • Looking for an air purifier to help odor in a small medical clinic ->Not a Dyson. Seriously. Alen, Coway or winix.
r/dyson • Which air purifier is the best for a kitchen? ->Dyson in general is not known for high quality especially for the price they charge. Also their customer service is shit. The other 3 I listed are much better options. You’ll want as much carbon in the filter as possible. Alen VOC for example.
r/dyson • Which air purifier is the best for a kitchen? ->+1 for Alen. With that size room, the Flex model is perfect. Then I’d grab the “odor” or “VOC/smoke” filter to deal with odors. Just note that the flex doesn’t come with any apps or ionization like the other commenter. That starts with the 45i and 75i models. Also are great but are way overkill for your room.
r/AirPurifiers • I’m lost ->It doesn’t exist on the flex model. It’s purely mechanical filtration. Which is what you are looking for.
r/AirPurifiers • I’m lost ->Alen is the best. I got this deal. 2 in kitchen/living room and one in bedroom. Amazing for smell and pet allergies. Only downside is filters are $80-$100 but they last for around 6-9 months. I also buy extra filter covers to make them last longer. https://alen.com/products/buy-2-breathesmart-flex-get-the-3rd-free
r/AirPurifiers • I’m lost ->I like Alen - they're filters aren't too expensive, they're quiet, and use a lot less electricity than other air purifiers I've seen. I've had this model for about 7 years now and no issues. [https://amzn.to/3H6Nhu8](https://amzn.to/3H6Nhu8)
r/homeowners • Which filterless air purifier have you tried and would recommend? ->I have a Pyr. I got an Alen BreathSmart Flex on sale for my living room and it's made a world of difference. I have 2 Coways for other rooms too. Night and day diference.
r/AirPurifiers • Can anyone convince me that airpurifierers are not a uneccessary waste of money ->Thanks for the feedback guys. I went with the Alen flex and got it on Amazon so it’ll be here asap. No weird filter issues, ionizing BS, etc. and it moves air well for a room my size
r/AirPurifiers • I’m lost ->I bought a refurbished Alen Breathesmart Flex from the Alen website for about $100. Works fine so far. I thought I'd mention it since, if cost is a factor, you can't go too far wrong at that price.
r/AirPurifiers • Air purifier for home in Southern California - why is this so hard! ->Longtime allergy sufferer. Alen air purifiers are the gold standard. Choose the BreatheSmart model that is one level ABOVE whatever your room's square footage is, and chose any filter designed for allergens or wildfire smoke. Keep the fan on the thermostat running (with or without A/C) and buy the best filter for your HVAC.
r/Minneapolis • Wildfire smoke air filters? ->Not smart but I have two Alens and absolutely love them. I've had an older Breathsmart for 6-7 years and still works great. Recently bought a smaller one for my gym/mancave and it's also great. Won't look for another brand if I needed another one.
r/smarthome • Air purifier recommendation? ->Alen is the best. True hepa (yes, this matters), absolutely silent, legit CADR. Coway and Winix are right behind them. Anything with true hepa (h13) is worth your money. Everything else is not.
r/AirPurifiers • I'm on the hunt for the best true HEPA air purifier. Any suggestions? ->We have an Alen breatheSmart. I like it. It’s sensitive to changes. It reacts as soon as we light a candle or cook. We change the filter once a year.
r/Home • Best air purifier for home to buy today - What are your favorite choices? ->I have seen multiple questions around VoC and impact of air purifiers on them. I am writing this post to give some clarity on the same. (My first post regarding AQI monitors was well received:s://www.reddit.com/r/AirQuality/comments/1jo60ue/your\_aqi\_monitors\_are\_probably\_garbage\_and\_here/) (About Me : I am working on AQI sensors and Air purifiers for living.) VoCs or Volatile organic compounds can come from various sources including - floor cleaners, paints, new furniture, smoke, pollution and also farts. The sensor that you are using will differ for each manufacturer in how and which gas it is reacting too. ECo2(Estimated Co2) is also taken into account when they calculate the VoC number. So you as a consumer you cannot really tell when and how it is triggered why your VoC monitors are still high even though you have your Air purifier turns on . Here are some facts: 1. Cheaper air purifiers may just have an Air filter and not true HEPA filter. This is getting rid of particulate matters or PM2.5, 10, and 1. It is not removing VoCs. Even the expensive ones with just Hepa filter will not get rid of VoCs. 2. Your VoC monitor are sensing gases and accumulation of eCo2, which cannot be trapped in the generic Air filters. 3. There are specific filters like activated carbon or zeolite based air purifers that can help in getting rid of VoCs. These filters have Porus material that can absorb and trap VoCs removing them from the air. Photocatalyst based air purifiers can also remove VoCs from air by destroying it. 4. Ioniser based Air purifiers also cannot remove VoCs. It only helps in settling down the particulate matters suspended on the air. It makes these particle heavy and then it settles on the ground. You still have to vacuum it. 5. Other very important point is that the eCo2 weightage in the TVOC calculation is immense. That means even if you have Air purifiers and the place is not ventilated enough, it can trigger TVOC value. Air purifiers and Split are only recirculating the same air. You need to provide good ventilation or your air should recharge/stale air should go out with fresh air coming in. I hope this helps. If you have any questions regarding AQI, feel free to drop in a message in comments section. I will try to answer in my limited knowledge and capacity.
r/AirQuality • Why your Air purifiers are not reducing VoCs - Answering with facts ->I doubt any air purifier would be silent. Since they have motors, they definitely will have some db levels. The Alen breath smart looks good. Ensure to get it with VOC protector option. you can choose any air purifier as long as it has: - True HEPA filter - Deodorisers- activated carbon or zeolite based filter - good area coverage It has all.
r/AirQuality • Why your Air purifiers are not reducing VoCs - Answering with facts ->It checks all good boxes - True HEPA filter - activated carbon and zeolite based filter - good room coverage - no jargons and simple to operate This looks really great purifier. Only con I can see is the price - $765 . Since this is made in America, steep price is expected due to higher manufacturing cost.
r/AirQuality • Why your Air purifiers are not reducing VoCs - Answering with facts ->We upgraded to a shark matrix robot vacuum with 45 day auto empty tank (10 day) after researching which one was best on pet fur. It runs every day. I still use my Dyson animal once a week to get where the robot can't. Lint rollers everywhere 😅. "Control" is the right phrase, as there's still a lot of fur. And we have Alen Breathesmart for air purifier. Which also needs to be vacuumed off a couple times a month. And brush corgs several times a week. (We have 2 fluffy pems and 1 not so fluffy cardigan)
r/corgi • What's your ultimate setup for controlling dog hair in your home? ->We have an Alen HEPA that we’ve owned for over 7 years. A couple of filter changes but still running like new.
r/CleaningTips • What air purifier do you swear by? Trying to cut through the hype. ->I love mine too
