The Whirlpool® Whispure™ AP510 True HEPA Air Purifier ‐ Model AP51030K, has a long history of exceeding customer expectations. Little wonder. With an AHAM Certified¹ clean air delivery rate (CADR) that puts it at the top of its class in performance, the Whispure 510 delivers certifiably clean air in rooms up to 500 square feet, while its Energy Star® efficiency translates into more energy savings for you. Add to this, Whispure 510's reputation for ultra-quiet operation. Of course, the unit is going to be much more quiet at the lower fan speeds, but even in "Turbo" mode (one step above High), the Whispure 510 produces only 49 decibels of noise, where most competitive models produce decibels well above 60, and even as high as 66!

Whispure 510 technology is based upon the same expertise Whirlpool uses for creating all of its high quality, reliable air purifiers. Whirlpool's true HEPA filter removes 99.97% of particles to 0.3 microns, with less air flow resistance to reduce noise, and less power consumption to lower energy bills. The activated charcoal pre-filter further removes odors and gases to keep air fresh while protecting the life of the HEPA. Air is drawn in from the purifier's large front grille and released from a top air outlet for maximum delivery of filtered air – even if the unit is placed directly against a wall.

The Whispure 510 goes a step further by featuring a simple, yet comprehensive electronic control panel designed to be easily understood and promote ease of use. With the push of a button select one of 4 fan speeds, including a Turbo setting to clean air quickly. Or, with the simple touch of another button, the Whispure 510 goes into an 8-hour Sleep Mode that reduces fan speed for quiet, energy-saving operation while you sleep. After 8 hours, the unit automatically reverts back to its previous setting.

When it comes to filter changes, don't worry, Whirlpool has your back. The Whispure 510 provides progressive, 5-stage status indicators for both the HEPA filter and the pre-filter, so that you know well in advance when the filters are beginning to reach their useful end. Under normal conditions, the pre-filter will need replacement every 3 months, and the HEPA filter once a year.  5-Year Mfr. Limited Warranty.

Whirlpool Whispure™ AP510 Air Purifier Instructions ‐ Model AP51030K

General on Pre-Filter:

  • The pre-filter absorbs odors and captures large airborne particles that enter the air purifier. Therefore, regularly changing the pre-filter will keep your unit performing at its best, and preserve the life of the HEPA filter.

General on HEPA Filter:

  • Remember that the filter's service life is related to the volume of air that passes through the purifier and the amount of contaminants in the air. If your indoor air has unusually high levels of airborne particulates or contaminants, the filter's service life may be shortened.

  • Regular maintenance helps to prolong the life of the HEPA filter. Keep the area surrounding the air purifier clean, and be sure to change the pre-filter approximately every 3 months.
  • Replace the HEPA filter if you notice a significant drop in air flow or if the filter media is excessively darkened.

NOTE:   Do NOT immerse the pre-filter or HEPA filter in water ‐ they are NOT washable.

Very quiet and effective. Happy with purchase.

Great air prufier. First one last 7 years
The best air filter I've ever had and I had a lot of air filter over the last 6o years.
the machine is quiet, even on turbo. cleans the air and does a great job
I didn't rate this product originally, but am looking to purchase a second unit and this was rated at a 3 overall. I couldn't let that go. I purchased this unit, plugged it in, and it has been running flawlessly for about 6 months. I have gone through 2 pre filters. I move it downstairs where my parrot lives and in a couple of hours it clears up the room. It is noisy on the high setting, but I run it on low during the night. Very happy with the performance and didn't want one bad rating to overly influence. Also, it was the highest rated on consumer reports and is cheaper than the GE.
GREAT air cleaner, really quiet on low. Turbo speed is great during room cleaning, when dust is getting disturbed. EASY carry handle and Turbo speed make it worth the extra [$] compared to the other Whispure this size.
I have 2 of these and they work great for bedrooms around 350sf in size. And the filter replacements are very affordable if you buy the off-brand ones offered on this site. Someone also mentioned a complaint about a squeaky noise. It took 2 years for 1 of ours to do this after being set to HI for ~12hrs/day, but unlike what was mentioned in that review, you do have easy access to the motor inside where you can apply some WD40 or silicone for the bearing inside. 2 years later, still no squeak, easy fix if you're comfortable with a screw driver, and I'd still recommend it.
I have gone years suffering with allergies but not knowing I had them until recently diagnosed. I have listened to the allergist and bought not only two of these air purifiers but the bed and pillow encasings for dust mites and I have to say I didn't believe these things work but I can now say I was completely wrong! These products are amazing and they actually work! The air purifiers are worth EVERY penny and if either one broke tomorrow I would absolutely get another one..they are quiet and work FAST. I first got one for the bedroom, I vacuumed the entire room first, put the covers on the mattress and pillows and then turned on the purifier and let it run for a few hours before going to bed. That first night was all the proof I needed these products work just like they say they do. After having the 450 purifier in the bedroom for 2 weeks we ordered the bigger 510 (this one) for the living room with the same results. You can actually feel and smell the difference in the entire house and you can breathe! If you are on the fence or skeptical about buying one of these purifiers or the bed encasings don't be... JUST DO IT they work... you will not be disappointed.
Have owned two Whirlpool Whispure 510's for over 5 years. Both units have run continuously at TURBO practically 24/7. Prior to the Whispure's, we used Honeywell Envirocaires. The Whispure's design is absolutely outstanding, and, sorry Honeywell, the Whispure is superior to the round Envirocaire. The Whispure is unobtrusive with its ability to be placed against a wall. The air is drawn through the front and exits out the top of the back of the unit, creating wonderful airflow in the room with a highly effective air exchange rate. Love this model! Worth every penny I spent on the units and the filter costs since. I use both units in main open living space and, being easy to clean, they still look great! Honestly, one of the best purchases we've ever made.
Air purifier is not very loud at all.....seems quieter than the 250 model that I also have. Seems to help my allergies and asthma. On high it also works good to drown out the noise of thunderstorms to help my dog sleep too. So far so good with this unit.
This is the second Whirlpool Whispure AP510 I've purchased. Our first one is doing such an excellent job downstairs that I decided to get another one for upstairs. It's quiet and powerful. Just looking at the volume of debris trapped in the charcoal filter is proof to me that this unit works! It's a simple to use, no frills air cleaner. I've tried many models over the past 15 years and this one is by far the quietest. It's slim profile is a plus.
Bought another Whirlpool Whispure for downstairs. My first Whirlpool Whispure is 8 years old and it is still going strong. Great product, highly recommend!
It is a great product. My 6 years old son had severe sinus allergy for the past few months that couldn't get cured by antibiotics. I did a lot research and feel this is a good unit with a good price too. I am so glad I bought it. It is very effective. Our downstairs is very clean now, and my son's sinus allergy is almost cured. One feature I really like is that the air blows out from the top. So I can put this anywhere (even in the corner) in the house. I would like to mention that it is a little nosier at the lowest level than I expected. I am very sensitive to noise so I don't think I can sleep if leaving it on in our bedroom at night. In our case, I leave it on day and night in our living room downstairs and it works great.
