DC1100 Pro Air Quality Monitor

I purchased an IQAir Health Pro Plus a few months ago after suffering from a bad bout of bronchitis. I developed a variant of asthma which leads to coughing excessively when the air quality is poor. The IQAir has been a great addition to my home, but it bothered me that I had no scientifically objective way to determine how effective it was or how often I needed to use it.I purchased the Dylos DC1100 Pro to confirm that my IQAir was really working, and to get a better understanding of what the air quality in my house was. The first week I had it I found my baseline particle count in the home was about 160,000 particles per cubic foot. The outside air was running at 260,000. In the bedroom where I keep my IQAir, my count was 30,000. So I knew right away I was getting some benefit from it. I was also able to monitor what fan speed I needed to keep my IQAir running at to maintain a reasonable particle count. Running at speed 3 was working sufficiently.A week later we had a terrible bout of smog by the house. The outside air particle load shot up to over 10 million! I couldn't see more than a few feet in front of my house. I noticed that my IQAir was having a hard time keeping up with the smog and my bedroom was rising to over 80,000. So I knew I had to run the unit at full speed to get the count down.So I've been monitoring the counts closely and using the numbers to determine how often and at what speed I need to run the IQAir at for optimal efficiency. I've also been able to confirm that holding the Dylos up to the IQAir shows a count of 0, so I know I'm getting very clean air out of the machine. I've read that the filters on the IQAir last much longer than when the unit suggests a replacement. So rather than replacing when the light comes on, I'm going to rely on the Dylos to tell me whether I still have clean air coming out of the unit. I've read that some people have original HEPA filters in their IQAirs more than 8 years and still have zero particles blowing out of the unit. That is really amazing!I was curious to see how accurate the unit was, and today I had a chance to test it out. I had an IQAir rep come out to my house to evaluate my home for a whole house IQAir system, and he brought his $3,000 particle scanner with him. We went around the house measuring each room and comparing it to the Dylos. Both units were showing virtually identical numbers. So I know this unit is really accurate.I can't imagine going without the Dylos now that I have it. I check it every day to see how the air quality is, and I know when the numbers go up I have to do some things to adjust for it. For those of you who are suffering from allergies or asthma and find an air purifier to be of benefit, the Dylos is an invaluable tool to help you manage your air purification efforts. This is truly an amazing device that I highly recommend.

This device can't provide accurate count for PM2.5, due to the facts as bellow:1 The count is not accurate,as Air moisture and temperature will greatly affect the result. As we all know, Water is everywhere-even in the air.It seems that this device can not make a distinction between "water vapor&" and "particles".The device's reading is so high in raining days.The count of PM2.5 is not accurate, especially when the air moisture level or temperature is high.2 This device can not provide PM2.5 count based on the official FDA or WHO measurement---μg/m3.Some sellers says u could "transfer" or "calculate" betwent the reading from this device to "μg/m3"-----it's a huge misleading to buyers and it's impossible.The result from this device is uncomparable to all the official PM2.5 data.Lastly but most importantly,The manufacturer provide a VERY VERY POOR service,I wrote a number of emails to their "support" email to inquiry this product, but NEVER get any reply.PLEASE also keep in mind, this product only comes with a 90 days warranty. And u can't get refund even when u receive a defective product in arrival.I was told by the seller, if u buy this product with a corporate address, then the manufacturer thinks there is a possibility of this unit to be used in another country. They will still sell this product to you, with no warranty at all. Sure they won't tell you that when you buy it,they just refuse to repair it when something happens----------They told me that I bought a device with no warranty at all, coz I bought it with a corporate address,which means customers could not return the defective products or ask for repair it.It seems that many local or foreign buyers buy this products without knowing these technical issues and the warranty facts, so I have decided to translate my review into other languages by google.---------------------------From a very very unsatisfied customer----------------Este dispositivo no puede dar cuenta exacta de PM2.5, debido a los hechos como bramido:1 El número no es exacto, ya que la humedad del aire y temperatura afectará en gran medida el resultado. Como todos sabemos, el agua está en todas partes, incluso en el aire.Parece que este dispositivo no se puede hacer una distinción entre el "vapor y agua" y "partículas". Lectura del dispositivo es tan alto en días de lluvia.El recuento de PM 2,5 no es exacta, especialmente cuando el nivel de humedad del aire o la temperatura es alta.2 Este dispositivo no puede proporcionar PM2.5 recuento basado en el oficial de la FDA y la OMS measurement---μg/m3.Algunos vendedores dice u podía "transferir" o "calcular" betwent la lectura de este dispositivo para "g/m3" ----- es un gran equívoco compradores y es imposible.El resultado de este dispositivo es incomparable a todos los datos oficiales de PM2.5.Por último, pero lo más importante,El fabricante ofrece un servicio muy muy pobre,Yo escribí una serie de correos electrónicos a su "apoyo" de correo electrónico a la investigación de este producto, pero nunca recibe ninguna respuesta.Tenga también en cuenta que este producto viene con una garantía de 90 días.Y me dijo el vendedor, si la compra de u este producto con un domicilio social, el fabricante piensa que hay una posibilidad de que esta unidad que se utilizará en otro país, se siguen vendiendo este producto para usted, sin ninguna garantía en absoluto. ---------- El dispositivo perdió 90 días de garantía coz lo compré con una dirección corporativa, lo que significa que no podía devolverlo o solicitar la reparación, incluso a través Recibí un producto defectuoso en llegada.Parece que muchos de los compradores locales y extranjeros compran estos productos sin saber estas cuestiones técnicas y los hechos de garantía, por lo que han decidido trasladar mi opinión a otros idiomas por google.----------------------------------------------------------------------------------------该设备无法提供PM2.5的准确计数，由于波纹管的事实：1计数不准确，因为空气的湿度和温度，将极大地影响结果。正如我们都知道，水是无处不在，甚至在空气中。这设备似乎不能让"水蒸汽"和"粒子"之间的区别。设备读数是如此之高，在下雨的日子里。，PM2.5的计数是不准确的，尤其是当空气中的水分的水平或温度高。2此设备不能提供FDA官方或世卫组织measurement---μg/m3。基于PM2.5计数的。有的卖家说可以"转让"或"计算"betwent从这个设备的读数到标准单位"微克"-----这是一个巨大误导买家，这是不可能的。从这个设备是不可比拟的所有官方PM2.5数据的结果。最后，但最重要的是，制造商提供一个VERY VERY POOR服务，我写了他们的"支持"电子邮件查询本产品的邮件数量，但从来没有得到任何答复。还请记住，这款产品只配备了一个90天的保修。有人告诉我，如果由卖方u购买此产品的企业地址，制造商认为有可能，将本机在其他国家使用，他们仍然会卖这个产品给你，没有保修。 ----------我的设备失去了它的90天保修因为我买了它与企业的地址，这意味着顾客不能回或要求修复它即使顾客收到了有缺陷的产品在到达。这似乎不知道这些技术问题和保修事实，很多本地或外地买家购买此产品，所以我决定把我的翻译成其他语言，由谷歌。
