Philips FY3433 + FY3432 HEPA & Carbon Filter Set – Price, Compatible Models & When to Replace
The Philips FY3433 + FY3432 HEPA & Carbon Filter Set is a genuine Philips replacement part for the Philips AC3256, AC3257 and AC3259 air purifiers. At Sparemaster it costs ₹4,792 (MRP ₹5,990, 20% off), with a GST invoice and shipping across India.
Which Philips air purifiers does it fit?
Philips AC3256 (any AC3256/xx variant)
Philips AC3257 (any AC3257/xx variant)
Philips AC3259 (any AC3259/xx variant)
Check the model number on the sticker under or behind your purifier before ordering – filters are model-specific and a filter from a different series will not seal properly.
What the FY3433-FY3432 filter does
It is a set of the two filters these purifiers use together: the HEPA filter (traps fine dust, PM2.5, pollen and smoke particles) and the active carbon filter (absorbs odours, smoke smell and gases). Changing both together restores full performance and costs less than buying them separately.
When should you replace it?
Your purifier counts filter hours and shows a filter-replacement alert when the filter is used up; some models stop running until it is changed. In Chandigarh and North India, winter smog and Diwali smoke load filters much faster, so the alert often comes earlier than the usual one-year life. Signs it is due: the alert light is on, airflow is weaker, the purifier stays on high all the time, or a smell comes back.
After fitting the new filter, reset the alert – see our guide When to Replace Your Philips Air Purifier Filter (and How to Reset the Alert).
Genuine vs duplicate filters
Cheap copies often use thinner media, little or no real carbon and a loose frame that lets air bypass the filter – the purifier's AQI reading stays high and the filter-life counter no longer matches reality.
