Whirlpool Whispure AP51030K Air Purifier Review

The Whirlpool 510 (AP51030K) Whispure true HEPA air purifier is made for rooms up to 500 square feet (46.5m). This unit is within a $200 – $350 price range and has very good ratings. Let me show you is it worth your attention.Whirlpool Whispure Air Purifier, HEPA Air Cleaner, AP51030K


  • Covers quite a big space
  • High CADR ratings
  • Filter system really works, ideal for allergy, asthma sufferers, and general air quality
  • The HEPA filter should be changed only once a year
  • Sleep mode


  • Big size. The air outlet on the top compensates for that a little bit because you can place it close to the wall.
  • Loud on the highest speed

Design, size, placement

Whirlpool 510 is quite big as a room air purifier. It looks like a heater, not very stylish. But it is a very smart design, the air inlet is in front, but the outlet is on top. So you can place it close to the wall, which allows you to save space. Also, Whirlpool 510 has built-in handles to transport the air purifier. Weight is 25lbs (11.3kg) which is ok for this size air purifier.

Height 24in (61cm), width 20.5in (52cm), depth 10in (25.4cm).

How it works and what sources of indoor pollution destroy

Whirlpool AP51030K has a fan that moves air through 3 filters. A fan is a weak part of this unit. Many customers had problems with noise coming from a fan. That is because the fan is not balanced. If you have one of them then you got a brack. Mine works very well.

The Whirlpool 510 has a 3-stage filtration system. Pre-filter captures large particles and helps to extend HEPA filter life. A carbon filter eliminates odors. The carbon filter is too thick to eliminate the high amount of odors, but low ones get rid of very well. In the middle is a true HEPA filter and it filters 99.97% of particles that are 0.3 microns and larger.

So with Whirlpool 510 filter system, you will eliminate dust mites, mold spores, pollen, tobacco smoke, pet dander, low odors, and other microscopic irritants that can pollute your indoor air and aggravate allergy and asthma symptoms.


  • This unit has electronic controls and 4 fan speeds. The buttons are plastic and look cheap, but I think you will not play with them very much.
  • The turbo setting is good for fast cleaning. It is loud, though.
  • A very good feature is sleep mode. When you push it, the purifier switches automatically to the low setting for 8 hours. After 8 hours, it goes back to the previous setting.
  • 2 Separate Filter Replacement Lights indicate when to replace the HEPA filter or charcoal pre-filter
  • Built-in Handles to transport the air purifier to any room in the house
  • Manufacturer’s 5-year Limited Warranty
  • Energy star qualified

Noise level

It’s quiet in the-the low setting, annoyingly loud in the top one.

I may suggest using a medium setting during the day and low in a night. Use the highest speeds only for specific circumstances.


CADR: Pollen scores 401

CADR: Dust scores 325

CADR: smoke scores 315

If used in a recommended size room of 500 square feet and let’s say ceiling height is 8 feet, then this air purifier gets rid of smoke, dust, and pollen in just 10 minutes. Really amazing. Imagine how good it works in smaller rooms.

Maintenance and upkeep

The manufacturer recommends changing the pre-filter every 3 months. I suggest vacuuming this filter every 2 weeks. That will save you money. Of course, they are not very expensive, 4-pack costs around $30.

The HEPA filter should be replaced once a year. 

Filters change is easy.

Whirlpool 510 is energy star qualified. Really low energy consumption for that big unit.


The Whirlpool 510 is a true HEPA filter air purifier with one of the best value general air purifiers on the market. It covers 500 square feet of space and costs between $200 – $350.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one. During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry. I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
