@AirPurifierFirst 2 года назад

Sure thing!

@Inisfad 3 года назад

Just a suggestion - I bought this great air purifier, and love it. But my suggestion is, when you are going to clean the pre-filter, either vacuum it while the filter is ON the machine, or, if you are going to wash it, take the filter outside to remove the filter. If you remove the filter inside your home, all the larger dust particles that it has caught, will be thrown back into the air.

It would be interesting to see the purifying effect with the lowest speed setting. Is the effect same as with the high speed setting but it takes longer time to clean?

@AirPurifierFirst 3 года назад

Yes, it is, but it's a little bit slower and less powerful than on the third speed. The best you can do when using an air purifier is to combine all speeds, depending on air quality in the room.

@hankwangn 3 года назад

With your noise measurements at 5:19 , what was the distance between the microphone and the purifier unit? The industry standard is 1 m (3 ft 3 in), well away from reflecting walls and ceilings. The image for speed 2/3 looks like the microphone is right on top of the exhaust.

@AirPurifierFirst 3 года назад

The distance is about 15.748 inches (40cm). We had in mind thing some people will use it just right next to them or on their working table. So, it's much more closer than industry standards suggest. But, thank you very much for that information. We'll keep it in mind, for the next reviews we do, for air purifiers, which are used for bigger rooms.

Since this purifier has an ionizer, it means dust are more likely to fall onto surfaces which technically "purifies the air", do you notice any layer of dust on surfaces in the room? I think it'll be a good future test but may be time consuming.

@AirPurifierFirst 3 года назад

No air purifier device will suck dust from the surfaces. But, when using air purifier you will notice far less dust in the air and you will breathe with ease. Also, after a while, you will notice less dust onto the surfaces.

@canuck21 2 года назад

Does it really has an ionizer? I looked at various sites and ionizer is not mentioned anywhere.

@SpykeZ0129 2 года назад

@@canuck21 No it doesnt. From their own FAQ, which apparently was too hard for the OP to look up. Do Blueair air purifier have an ionizer? An ionizer, or ionizer air cleaner, uses a high-voltage charge to produce and emit ions into the room as a means of cleaning the air1. The by-product can be ozone, yet at very low levels, as all household air cleaners sold on the US market must follow stringent regulations for ozone emissions. Instead of emitting ions into the room as a means of cleaning the air, Blueair air purifiers use a combination of mechanical and electrostatic filtration to remove even the tiniest particles (down to 0.1 μm) from indoor air. We call our filtration technology HEPASilent™. Whereas an ionizer, or ionizer air cleaner, uses a high-voltage charge to produce and emit ions into the room, Blueair’s HEPASilent technology, uses a fan to draw charged airborne pollutants into the air purifier so that they stick more effectively to the filter. This increases the filtration efficiency of Blueair air purifiers, while at the same time achieving a higher Clean Air Delivery Rate (CADR) and more silent and energy-efficient operation.

@AirPurifierFirst 2 года назад

I have talked with Blueair support several times, and they state that every Blueair air purifier has an ionizer built-in. It’s called HEPASilent technology, and it is a combination of electrostatic and mechanical filtration. You can also confirm this if you read the Bleuair 411 energy star certificate results.

Would this help with the stench in my bathroom after I go #2? My wife and kids complain they can't enter the bathroom for up to 2 hours and 35 minutes (we timed it) because my farts are so putrid. Last month, two of my kids passed out when entering, like within one hour after I finished my dump. I forgot to warn them with the post-it note on the door like we agreed I'd do. My wife found them passed out on the bathroom rug in the doorway unconscious. She had to crawl dragging them to safety in the hallway for fresh air. I guess I've become immune to my own gas so it doesn't bother me the same way. 🙄💩

@TiredMikee 6 месяцев назад

No, HEPA and electrostatic filters cannot remove odours. You would need to find an air purifier that has a significant amount of activated carbon to adsorb the odours. Examples include the Austin Air Healthmate or Healthmate Plus, IQ Air HealthPro Plus, and IQAir MultiGas. The Winix 5500-2 or an AirDoctor would also help, but you would need to replace the carbon filters more frequently than the other models I mentioned. Good luck 🤞

At 3:22 you claim it's a HEPA filter (99.97% efficiency). It's not. The marketing material of the manufacturer leads you into believing that the Blue Pure line uses the same filtration technology as the more expensive offerings, which have a corona discharge ionizer upstream of the filter. Nowhere on the Blueair website there is any statement about the filtration efficiency of the Blue Pure 411 or 211 device. Not that it matters that much, since the clean exhaust air is mixed with the dirty ambient air anyway.

@@hankwangn I think you are right. The Amazon sales page for the 411 does not mention HEPA silent. Only their Classic ones do. I can't understand the patent well, but if I understand correctly, the only way to ensure ozone and negative ions are not getting into the ambient air is if the charged air passes through the filter before leaving. But the 411 seems to have the air pass through the filter and THEN get charged, and then is released to the room. So this seems to pose the safety hazard of the having more particle get deposited in the lungs: www.sciencedirect.com/science/article/abs/pii/S0304388697001344 Do I have all that right? Also, I emailed the company a couple days ago asking if the new 411 Auto coming out had 99.7% efficacy as their Amazon ad claimed. Next day, the Amazon ad was gone.

@@hankwangn you're right, thats a play on words. its not a true HEPA filter. It just runs very quietly like one, very quiety. Also it's does not ionize the air at all! I have two 411's and one 211+. I've had them for about 4 years now.

@mikesmith-yx4xb 3 года назад

I see the filter is not washable so it's not a good buy until they make one.

@AirPurifierFirst 3 года назад

Why not? The filters in Blueair 411 are effective and even more effective than some washable filters.

@@AirPurifierFirst I specifically bought the BlueAir just for the fact that it remembered the state after power loss. A lot of air purifiers will reset when power goest out.

Yes, the 411 has that feature, as well as the 211+, which video review I will publish next week.

See these air purifiers with the smoke test aren't really real they really don't work in real world tests with smoke in the room it will help yes but not as good as these tests

@AirPurifierFirst 3 года назад

Hi @pavy415, thanks for your comment. Smoke box presentation is real, and, ordinarily, air purifiers do not work as same as in the smoke box, because all rooms are far more spacious than this smoke box. Anyway, many factors are deserved for efficient air purification in the room eg, room size, air purifier airflow, the size of carbon filter, etc.

If you’ve never used an air filter these are great. ru-vid.comUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!
