First time buying this particular coarse dust filter, but it looks and feels just like the ones I'm currently using, and at a cheaper price. ### ⭐⭐⭐⭐⭐ Must have *by J***G on 7 June 2026* These are a must have for my IQair 250 machine. Extends the life of my pre filter compared to when I do not use these. They have always fitted well and are easy to wash, so I get another go out of them, as long as I don’t leave them on too long. Highly recommend ### ⭐⭐⭐⭐⭐ Great Replacement pre-filter for IQAir Purifier *by S***L on 8 May 2026* I have purchased these filters several times. They are the pre-filter that goes on the bottom of my IQAir Air Purifier. I change them out every 2 to 3 months and they help save the life of the larger IQAir filters. They fit my machine perfectly. Installation takes less than 2 minutes and is a breeze. They go on the bottom outside of my purifier where the airflows into the machine. This filter captures the dust and larger particles before they reach the inner filters. So they are an absolute necessity IMO. The airflow is not inhibited in anyway. Great value for the money. I highly recommend them. ⭐️⭐️⭐️⭐️⭐️ experience. ## Frequently Bought Together - Smilfil 5 Pack PF40 Replacement Pre-Filter Pads Compatible with IQAir PF40 Coarse Dust Pre-Filtration Air Purifier - IQAir PreMax Prefilter - Genuine Replacement Air Filter For IQAir HealthPro Series - Controls Coarse and Fine Particles - Dust, Mold Spores, and Powder - Swiss Made Filters For Air Purifiers - IQAir 3-in-1 Filter Bundle - Genuine Replacement Filters for HealthPro Plus System - PreMax Pre-Filter - V5 Cell Gas & Odor Filter - Patented HyperHEPA Filter - Swiss Made Filters for Air Purifiers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/503728687-smilfil-5-pack-pf40-replacement-pre-filter-pads-compatible-iqair](https://www.desertcart.sg/products/503728687-smilfil-5-pack-pf40-replacement-pre-filter-pads-compatible-iqair) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-27*
