Alen T500 Price

Alen had a happy year thanks to the release of their new flagship – the Alen BreatheSmart 75i. But back to many years later, this brand has a good product line of tower air purifiers, which is trusted by many customers for the price – the T100 and T300. Now both of them are discontinued by the company, so they can improve and focus on the latest device – the Alen T500. This is also one compliment, because other American brands like Honeywell and Guardian Technologies are still keeping their old models. It’s hard to keep track for new updates and the availability of the very old models, so I love Alen for not being too greedy.

The American brand brought out the Alen T500 with an even more attractive price tag than the predecessors. In Breathe Quality, we believe that is a smart move from Alen. Despite of the perfect customer services, a $300 tower air purifier needs much more to be profitable. With only $199 in Alen website, the Alen T500 is more practical to buy.

This air purifier is mostly to extend the customer base to those who are willing to spend more, but still need a low-range air purifier. Well, it is nice to have a lifetime warranty for an only $199 Alen T500, right? That’s truly the selling point of Alen, because with $199, they put their Alen T500 directly into a massive competitive segment. That price is around the same with the Levoit LV-PUR131 and Coway AP-1512HH, which are unquestionable great for customer services, too. I don’t want to list a series of competitors, but keep in your mind, the list is longer more than you can imagine.

At $199, the Alen T500 can be replaced by the newer Alen BreatheSmart 25i for having new air flow approach. But we are here because we want to know the Alen T500, so let’s save one deal for this air purifier first, as the Amazon’s Choice air purifier is only $155 with this deal.

Alen T500 Design and Size

The Alen T500 has a very similar appearance to the previous T300, but for most of Breathe Quality’s readers who search for an Alen device the first time, I will describe it thoroughly. Being the middle between the T100 and T300 (funny, isn’t it), the Alen T500 has a very classic design that matches the first tower air purifiers from, yep, all other American brands. Guardian Technologies has the GermGuardian AC5250PT and Honeywell comes with the Honeywell HFD-120-Q. Testing and using air purifiers for many years, even me can’t tell the different if just glance at this Alen T500.

Standing tall with 22 inches in height, the Alen T500 is the same size with the compact GermGuardian AC4825. Also with only 9 lbs in weight, this air purifier is portable and convenient to move around. Alen has made a $39 travel bag for only this Alen T500, so you can easily pack it up and bring it with you anywhere. I have not tested the travel bag, because it is not included in our sent air purifier, so you need to search for the Alen T500 Travel Bundle to get this bag.

Also, there is a white version of this Alen T500, which is not usually available to buy. You can grab one with our deal.

Our today Alen T500 is a true tower air purifier with the classic design for back-to-front air flow concept. That being said, we have one big air intake grill from the back and the opposite air outlet grill. This concept is useful for tower air purifier, providing that they don’t have the ridiculous panels like some of GermGuardian air purifiers.

On the top is the intuitive LCD Screen controls with 4 basic function buttons to help operate the Alen T500 easier. The curved head gives me the feeling of similarity to the GermGuardian AC4825, but I don’t think they’d be important to compare. Personally, I don’t enjoy this top control, which is hard to push the buttons. If I need to choose one, the design of the Honeywell HFD310 is much better.

There are many panel color options available for you to choose, from the basic Black and White versions, to the distinctive and special from the both sides: Black Espresso, Black Oak, Black Rosewood, White Maple and White Oak. Our testing unit is the Black edition, but you can get others from Amazon as well.

Alen T500 Filters

As the decisive criteria for the performance of one air purifier, by default we look at the quantity and the quality of its air filters, and what the air filter types are using. The Alen T500, along with most of other Alen air purifiers, has a 3-stage air filtration system. The first layer is a washable pre-filter, while the second stage relies on a HEPA air filter. There are 4 different HEPA air filters to choose from.

1. Pre-filter – Simple pre-filter that traps large pollutants.
2. True HEPA filter – The Alen T500 captures 99.97% of particles as small as 0.3 microns. Choose from four specialized configurations:
   • HEPA-Pure – The standard HEPA filter of the Alen T500.
   • HEPA-Fresh – The next level HEPA filter will improve the first HEPA-Pure to deal with the household odors like cooking smells and light smoke, with an addition of Activated Carbon filter.
   • HEPA-Silver – For a little bit more money, you can upgrade to the HEPA-Silver filter with anti-microbial Silver-Ion threads that prevents the growth of mold spores and bacteria.
   • HEPA-OdorCell – The ultimate level HEPA filter of the Alen T500, using the ultimate Alen’s Molecular Conversion Powder. This air filter is the final defense against all allergens as well as smoke and pet odors.
3. Ionizer – To improve the performance of the Alen T500.

Let’s talk about the 3-stage air filtration system of the Alen T500. The polluted air first needs to pass through a washable pre-filter to capture large particles like large dust and pet hair, which is permanent to use and able to extend the life of the HEPA filter.

Next stage, while having 4 different levels of HEPA air filter to choose, here’s where the Alen T500 starts to fall down. The Alen T500 now uses a True HEPA filter, that is capable of dealing with 99.97% of any as small as 0.3 microns in size particles. While the HEPA filter is great, after all it is certified to guarantee the purification, I’ve encountered performance issues with the Alen T500.

The last stage, we have one ionizer which is used to increase the efficiency of the HEPA filter. However, it doesn’t help many. I’ve found that some intensive activities have proved a struggle for the Alen T500, and whatever I turned the ionizer on or off, the efficiency of this air purifier remains the same. For a $200 air purifier, you can expect much more from others like the Levoit LV-PUR131, Airmega 200M and Honeywell HPA200. They offers better True HEPA filter, and better fan power as well.

In 2026, we rework the air purifier ranking list, and the Alen T500 must take a more difficult test, both because it has a new True HEPA filter, then because the old test should be for cheaper air purifiers. As you can see, the Alen T500 did a good job at capturing 98.93% of all particles down to 0.3 microns, after 1 hour. It is better than new air purifiers like the Shark HP152 and Shark HP102PET, but not as good as the Frigidaire PureA300 XL.

Sadly, the air filter cost is not cheap. For the first level of HEPA-Pure, the air filter cost starts at $44 for a single pack. The HEPA-OdorCell is up to $89, and whether I choose the $45 from the Coway AP-1512HH or $49 from the Honeywell HPA200, it is much better, plus that is the price tag of a True HEPA filter. Thankfully, the True HEPA filter of the Alen T500 can last for 1 year, effectively increase the Annual Cost ranking.

Alen T500 Room Coverage

The room coverage of the Alen T500 is nothing to write home about – if anything it’s a little bluffing. The room coverage in the manual is 500 square feet, but I will tell you why the air purifier is insufficient for that number.

The ACH of the Alen T500 is 5X. The Alen T500 has better air changes per hour for a very smaller room size, just 79 square feet. If you use the Alen T500 in a room of 500 square feet, it will only clean your room once per hour.

The CADR of the Alen T500 is 142 Dust/ 121 Smoke/ 159 Pollen (cfm). There is no need to tell you that with such low CADR rating, the Alen T500 is really insufficient for such large room as 500 square feet in area. The CADR rating is still better than the Levoit LV-PUR131, but is lower than any other $200 air purifiers.

Alen T500 Sound

One reason Alen gave to public for not having True HEPA filter is because they don’t want the True HEPA filter restricts airflow. It is quite reasonable, and with less restriction in the air flow, you don’t need a powerful fan to cover a large space.

Source: Amazon.com

However, it is not for, at least, the Alen T500. Even without an impressive fan power, the Alen T500 makes lots of noise. In the lowest fan speed, we have a tolerant noise level of 42 decibels, which is a little bit higher than the standard library noise level, but it is still okay to me.

Once you switch to the highest setting, the table is turned. The noise level of 56 decibels (db) is unexpected high for an air purifier like the Alen T500. Moreover the crackling noise from the ionizer makes things worse.

If you are running this air purifier in quiet places, I totally don’t recommend it.

Alen T500 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is meant to run for a long time to be efficient, that’s why many air purifier brands consider the energy-saving standard, mostly in the rate of Energy Star, is one important selling point.

The Alen T500 has an average power consumption, with the maximum not above 53 watts. The power consumption of the Alen T500 is stable, and if you know the Honeywell HPA200 consumes 84 watts for the same price, you may have more good feeling toward this Alen T500.

And yes, the Alen T500 is one of the few models getting an Energy Star rating from Alen. Though at the moment you can’t find the model on EPA website anymore, this is still a good air purifier to get.

For using a Alen T500 8 hours per day, it would cost you about $20 per year.

Alen T500 Additional Features

The company makes the Alen T500 to be the budget device among the army of Alen air purifiers. That’s why you can’t find the latest modern features like Smart Sensor and Smart connectivity, which are common in the $200 GermGuardian CDAP5500BCA or Blueair Sense +. But again, many air purifiers within the price don’t have Smart features, either.

Fortunately, we are having a necessary Timer and LED indicator for filter replacement. These basic features are truly needed to have one air purifier operate smarter. But yes, you only have these additional features when buying an Alen T500. I know, there is always something you don’t think you’ll miss until you lose it.

Alen T500 Customer Service

Running through a very long review about Alen air purifiers, you may question us: “Why I need to buy Alen air purifier?” Yes, if it is not for the outstanding performance, or the top-class fan power, then there is must be something really, really important. What I’m trying to say here is the perfect customer service from the Alen Corporation.

Alen doesn’t hide the intent to speak high of their customer services. Look at their website, there are full of content to support the customers. You will have their phone, their emails, and of course, their support policies without any hindrance. To reach the Alen, you can contact them 6/7 days per week. They provide the best fast and free shipping for any products, as long as the orders are placed before 3 PM, they will guarantee to ship in the same day. Impressive, right?

They expand the refund time up to 60 days, or 2 months. You won’t need to worry about the quality of your air purifiers, because Alen will back you up with 3-year warranty (not Forever Guarantee anymore). Whenever your personal Alen air purifier doesn’t operate as normal in the third year, you will have a same refurbished air purifier with free shipping. To do this, please call 512-436-0457.

There are a lot of good reviews for the Alen customer services, that’s why I highly recommend to look for the brand if you need better air quality for your home.

Our verdict

With a True HEPA filter, the Alen T500 now deserves the price. However, it still has a weak fan power and is very noisy. But Alen is the top 1 candidate for the best air purifier customer service in the world, and you should never take it lightly.
