Are you in the market for an air purifier and wondering what the Whirlpool Whispure AP51030K is like? The first thing you want to know is that it has been renamed and is now known as the WP500P. This air purifier has 4 fan speeds as well as electronic controls. The manufacturer promises that it will clean 99.97% of germs in the air, thanks to the true HEPA filter. Some of the features that draw me towards this unit are close to silent operation.

In this article, we take a look at what makes this unit something you should consider, and also what could have been done better. Let’s dive in, shall we?

Whirlpool Whispure AP51030K


The Whirlpool Whispure WP500P is a neat unit with a louvred front end. It comes in pearl white and also black. The design is modern and contemporary and aesthetically pleasing. It will fit in with most décor schemes. The front grill, however, can easily trap dust and will require dusting. The other downside is that it only comes in white and black which may clash with your room colors, but chances are it won’t. 

It has an electronic soft-touch panel, which makes the unit look advanced and cutting edge. 

Sizes- What important numbers do I need to know about this unit

The Whirlpool Whispure WP500P measures 20.5 inches by 10 inches by 24.13 inches. When it comes to air purifiers, CADR rating is an important feature to check on. For smoke, it has a CADR rating of 315CFM, a 325CFM rating for dust, and a 401CFM rating for pollen. It will cleanrooms up to 490square feet.

This air purifier is made for large rooms. Placing it in smaller spaces, smaller than 490 square feet, may land you in a precarious position of having a unit that is too powerful for a smaller space. Anything smaller than 490square feet will be overwhelmed. 

Feel-How does it clean the air and how well?

This unit uses HEPA filters, which help filter particles as small as 0.3microns. Meaning that I can trust it to clean the air of very small particles, that ordinarily cannot be seen by the human eye, or cleaned by hand for that matter. It helps remove odors, dust, pollen, pet dander, and also prevent the occurrence of allergies caused by impurities in the air. It also captures mold and spores. 

The air purifier uses 2 filters to clean the air, a True HEPA filter as well as an active carbon filter. The active carbon filter will filter the air of the larger particles and pre-clean the air before the true HEPA filter gets to work. The true HEPA filter cleans the air of the much smaller particles such as pollen. The active carbon filter is what also helps to remove the odors. 

It has four fan speeds to clean the air, these range from low, medium, high, and turbo. The turbo setting lets you clean the air quickly and effectively. Also, this air purifier is very quiet as it runs. One of the few disadvantages of it is that at the highest speeds, it makes noise that is noticeable. 

This makes it a good buy to use through the night, in a bedroom, or a nursery, or if you just don’t like the constant reminder that there is an air purifier in the room. The best units on the market should make a difference in the room without announcing that they are there. It should be felt rather than heard. 

The good CADR ratings that this unit delivers, means that you can effectively clean the air in a large room(about 490 square feet) once every 12 minutes. One of the great things about this air purifier is that it has a sleep mode which lets you sleep through the night without any noise.

Durability of the Whirlpool Whispure AP51030K / WP500P

You will need to replace the HEPA filter once a year. whilst the active carbon filter will need to be replaced once in three months. It comes with a five-year limited warranty, as long as you use genuine whirlpool filters and parts. 

The unit has a filter indicator that shows you when a filter needs to be changed. This way you don’t overuse the filters and possibly wear out other parts in the machine. 


The Whirlpool Whispure is an efficient air purifying unit, that can clean large rooms such as your living spaces, of even the smallest particles. With this in mind, you would expect to pay an arm and a leg. However, that is not the case with this unit. It is fairly priced and is worth the penny spent.

It’s a high performing air purifier at a low-end price. Word on the street is that it would be difficult to find anything cheaper. But that’s always a challenge I’m up for, if it is indeed the most affordable, that’s great, if it isn’t, you still get an efficient machine. As long as the machine does its job, it’s a win-win. 

The other feature that makes this a good buy is that it is an energy saver. When you look at the price of an air purifier it is important that you consider the cost of running it as well. This unit is highly efficient even in terms of energy. Whilst the exact amount that you will use on power depends on your power company, the less energy that you use, the less you will pay. This drives down the cost of running the air purifier. 


This air purifier is effective especially for clearing the air of any potential causes of allergies such as dust, pollen, smoke, and other particles that may be too small to see with the naked eye, let alone clean. The Whirlpool Whispure AP51030K also known as the WP500P is an air purifier that cleans the air efficiently and effectively. The electronic controls are easy to read and to use. You won’t need to get out your manual each time that you need to use the unit. 

This is an air purifier I would consider getting because of its affordable running costs and high efficiency.
