Review on 🌬️ HEPA Filter Replacement for Whirlpool Whispure Air Purifier Models AP450 AP510 AP45030HO with 4 Pre-Carbon Filters - Replaces Part # 1183054 by Adam Gambel

I understand why so many customers are reporting unusual odors from the pre-filter. I've been using this product for several months and noticed a slight "vinegar" smell within a few hours of installing it. This strange smell will disappear after about a day, after which the product will work as expected. I figured that putting up with the weird smell for a few hours while the filter was vented was worth the significant cost savings. Another odd thing, the factory pre-filter is a bit too big. It still fits my Whirlpool Whispure air purifier, I just had to fit the extra materials into the Hepa filter frame. All in all, not perfect, but for a great price, it gets the job done. By the way, the Hepa filter part fits perfectly and doesn't give off a weird vinegar smell.
