Photo of Two Whirlpool Air PurifiersAs you may already know, Whirlpool is the #1 selling appliance brand in the United States.

It’s no wonder then that the company has had two air purifier products that have continued to top the charts with consumers.

These two popular HEPA air cleaner models are:

  • Whispure AP51030K (Also known as the Whispure 510)
  • Whispure  AP45030K (Also known as the Whispure 450)

With a combination of more than 1,200 positive reviews and a near 5 star rating from customers, it’s clear that Whirlpool has developed a set of amazing air purifying products that deliver powerful results.

However, there’s one major problem you’ll find when it comes to these two devices.

From the onset, these two machines seem practically identical and trying to figure out which one is better for your individual needs can be quite a challenge.

While it’s true that these two air cleaners are outstanding devices, the comparison between how each is different is not clearly defined by many online retailers.

Our goal in this review is to show you exactly how these two Whirlpool Whispure air purifiers are the same and in which ways they’re different.

With an average price difference of $50 between these two devices, knowing which air cleaner includes the features that are best suited for your home or office makes this decision even more important.

Below, you’ll find everything you need to know about these two products. By the end, our hope is that you’ll have a clear understanding of which one to get.

Similarities Between the Whirlpool Whispure AP51030K and AP45030K

Pointing out how the Whirlpool Whispure AP51030K and AP45030K are alike is the easiest step in this review.

In fact, these two air purifiers have so much in common that you may wonder why Whirlpool even designed two different products.

We’ll get into the subtle differences in the next section, but for now, here are the features that you’ll enjoy no matter which Whispure air cleaner you buy:

  • Three Stage Air Filtration – This multi-step process traps the most amount of harmful particles. It includes a pre-filter, carbon filter and True HEPA filter.
    • Pre-filter – This traps the largest particles, such as hair, pollen and larger dust, and prolongs the life of the True HEPA filter.
    • Carbon Filter – This absorbs and removes odors from pets, cooking, chemical cleaners, mold and more
    • True HEPA Filter – This is the gold standard for air filters. It captures particles as small as 0.3 microns. This includes ultra-fine dust, allergens, bacteria, mold and other airborne contaminants that cause breathing issues.
  • Filter Replacement Indicators – This alerts you when it’s time to replace each filter.
  • 4.8 ACH Rating – ACH stands for “Air Changes Per Hour.” This rating indicates how many times the air is filtered within a room every hour. 4.8 ACH is a good rating.
  • 315 CADR Rating – CADR stands for “Clean Air Delivery Rate” and was developed by the Association of Home Appliance Manufactures. The rating number equates to speed. Higher ratings mean that the device is faster at cleaning the air within a room. The maximum CADR rating is 450.
  • Quiet Operation – As the product name hints, these Whispure air purifiers are nearly silent.
  • Energy Star Label – This seal ensures that you’re getting an energy-saving appliance that doesn’t sacrifice on performance.

Differences Between the Whispure AP51030K and AP45030K

Now that you know which features the Whirlpool Whispure 510 and 450 have in common, the differences are easier to pick out.

As we mentioned earlier in this review, the average price difference between these two air cleaners is around $50, with the AP45030K being the cheapest.

Once you see how minimal the differences really are between these two air purifiers, you may question if the AP51030K is worth the extra cost. For some people it is, but for others it’s not. We’ll let you decide.

Here’s a list of the key differences:

  • Average Price: $279
  • Can purify the air up to 500 square feet. This is roughly the size of a 25′ x 20′ room.
  • Has 4 fan speeds, including a *turbo option
  • Includes a sleep mode for whisper quiet operation while you rest
  • Operates with push-button controls

*Turbo mode is often only used when a sudden influx of airborne contaminants enters into a room and you want to get rid of them quickly. For example, smoke or odors from cooking, an open window that allowed plant pollen to rush in, or after a large amount of chemical sprays or solvents were used in a room.

  • Average Price: $229
  • Can handle rooms up to 490 square feet (almost identical to the AP51030K)
  • Has 3 fan speeds – low, medium and high
  • Operates through a rotary dial control

Final Comments

As you can see from the comparison lists above, the AP45030K can purify practically the same amount of space for less cost.

While the turbo mode on the AP51030K is a nice feature, it’s not a must have by any means.

The same thing goes for the sleep mode. The AP45030K includes a low mode, which is just as silent as that feature. The only difference is that the sleep mode operates on an 8 hour timer and automatically puts the air purifier back into the fan speed it was at before it went into sleep mode. If this feature is important to you, then the AP5030K is a better choice.

The only other comparable feature is the difference between using push-button controls versus a rotatory dial. While it’s true that a dial is a step backwards in innovation, you have to ask yourself if push-button controls area really a deal breaker for you?

Hopefully this review and comparison of the Whirlpool Whispure Air Purifier HEPA Air Cleaner AP51030k versus the AP45030K has helped you decide on which product is best suited for your home or office needs. Regardless of the device you do choose, you can rest assured that you’re getting a superior air purifying device that will keep the space around you fresh and clean.
