PUREBURG Replacement Filter set Compatible with Whirlpool Whispure 1183054K 8171434K Fits AP450 AP510 AP51030K AP51030KB AP45030K WP500 WP1000 Air Purifier, H13 HEPA Activated Carbon

Fit my older whirlpool air cleaner perfectly. And it came with 4 perfectly sized pre-filters. Nice bonus!

The Pureburg filters fit my Whirlpool Whispure 510 perfectly! The price is so much more affordable than from the Brand manufacturer. The filters are sturdy and well-made. The outer filter, which needs to be changed every 3 months really traps dust and does a great job in keeping the air clean. I highly recommend these filters!

Works for my air purifier

This air purifier is excellent but don't wait for the red light signaling to change the filters which could "last" for years...... If you want it to help in times of need, it really is worth the expense to change the HEPA filters twice a year (like at the onset of spring and fall "fevers"), and probably the others four times. Like us, they work best when not struggling to pull in the air. Also, as the directions say, do not vacuum either filter to use them longer. Do it right and consider it worth the value for your well-being. After a particularly rough pollen season I learned this the hard way.I run my two (which I have had for about 9 years) 24/7 on medium, or even low. The space is fairly large. The units are near where I spend the most time, but the air circulates surprisingly widely. I have central AC, live alone, have no pets—so my units are not heavily challenged. In more difficult circumstances, all the more reason to keep those filters at their best.

The filter and carbon filters look well designed and fit well. So far it works well and is a good choice. Filters are just not sexy units. You want them to fit well and work well and this seems as if it will meet those standards. It's impossible to tell whether it's totally equal to original OEM unit but seems almost like the original filter.

Great filters. I use them all the time. when you see what they look like after a month or two you’re glad that that’s not in your lungs.

Perfect fit

Fit perfectly in my Whirlpool (Whispure 500).
