2887 review, pic shows my new and old HEPA filters
17 November 2016
After doing some research I narrowed my choices to Phillips 2887 and Honeywell. honeywell is a very good brand and very trusted brand. I didn't buy it for the only reason that it didn't have a true hepa. the second choice is this phillips, the point I didn't like about this brand is the placement of carbon filter, ideally it should be behind HEPA not infront as in this. i don't know why they missed this simple point, or they must have some reason for this which I don't know.
I brought this product yesterday from Bajaj electronics, who sold me this for 19000. It's too early to write a review, as I have used it only for 1day.
There is a difference in the quality of air that we were breathing, even though I can't independently quantify that result.
When I switched on for the first time pm2.5 indicator was showing 130, with half hour of usage it came down to 70. But the whole night the indicator never came to blue and the pm2.5 levels were around 50. Don't know why? Can anyone tell me whether it will be like that or we can expect it to comedown further?
Will write more review after using it for few months.
Update: after using it for a week, now I know the mistake I was making. Initially I was running the machine only in auto mode, that never used to reduce the pm2.5 to below 50.now I am running it in turbo mode for sometime, then I am switching it to fan level 3 for the whole night. By this the levels were coming down to 10.
Now about the feeling of quality of Air, I can tell you that I am feeling better and my quality of sleep has never been better.
A big note: I am a Doctor
Update 2: after 2wks of use I found out that pre filter is not of very good quality, as I am feeling it's not catching enough dust. I took out pre filter and carbon filter and kept it in sun for an hour and gave gentle tap, by this lots of finer particles got released. So conclusion: clean your carbon filter and prefilter, frequently every 10 days. HEPA filter also turned black somewhat with in 10days, and I am staying in Hyderabad. So this means even Hyderabad air is also not good quality.
Review after 5months usage: This is to report a strange problem that I am experiencing recently. I am getting burnt smell of exhaust air from airpurifier. I have removed all the filters and sun dried and put them back. Still that smell is persisting. Don't know the cause of it. Filters all are working fine since 5months. AQI is also normal. Will update you all as soon as I get to know the reason.
That burnt smell gone after few days, after I kept HEPA filter in sun.
Update @1yr - now I have decided to change both carbon filter and HEPA, my old filters are still working fine, AQI is also normal.
