Unlike the similar Phillips 1215/20 air purifier, this product does not have a pre-fliter and an activated charcoal filter before the HEPA filter. The pre-filter traps bigger particles and is cleanable. In a place like Delhi where hazardous air-quality is the norm pre-filter is a must. A simple HEPA filter like this has, will run out in a month or so. This will be very costly for regular users.

This product does not have a pre filter, Good service from Flipkart and Philips, Night mode is very quiet. I feel difference after using it. Best product and price

Have been using the product since the last 15 days. It works like a charm. Cleans the air perfectly well. During Diwali when the outside reading of PM 10 was above 1000 and PM 2.5 was around 700, the purifier took 15-20 minutes to turn the air quality of my closed bedroom (12x12 feet) from very dirty (red) to dirty (reddish violet). It took around 1.5 hours to turn to blue (safest level of the air sensor).
However, 4/5 days post Diwali, when the pollution level had subsided, the air purifier...

Very simple and elegant design, simple controls that anyone can handle. effective for average bedroom size. The difference is air quality is quiet evident. I live in Bangalore and pollen allergy is quiet common, I wanted to help keep the bedroom when my kids sleep safe from allergens and this air purifier seems to be doing a fairly good job. Filter change is something I'm yet to experience as the indication is yet to come up for filter replacement, so unsure of the running cost. However a reg...

Very happy with this purchase. Doing a lot of good for my house as far as air quals concerned. The amount of dust this removes is phenomenal, so yeah it works! You can feel the difference in air quality after using this, especially if your sensitive.The light sensor may be too sensitive/faulty, especially in low light but also sometimes even when rooms brightly lit during day the night/sleep mode gets activated.But its okay when all lights are out, it goes in & out of sleep mode in regular in...

The product is good and senses the air quality and displays the colour. Blue for good air, etc. But do not know is the sensing is correct or not. But overall it is a good product and kids are getting good air at least within home.

Using it for last 24 hours in a small 110 sq ft room. Not sure whether it's doing its job properly. As per its sensor, it is cleaning the air. But I don't feel any drastic change as of now. Liked its sleek and portable design.
