Apolnus One X Air Purifier Achieves Over ¥27 Million in Crowdfunding, Redefining Air Purification with Washable Filters
The Apolnus brand, developed by Joestech Co., Ltd., has launched its next-generation air purifier, the “Apolnus One X,” on the crowdfunding platform GREEN FUNDING. Since its launch on June 30, 2026, the project has garnered significant attention, exceeding ¥27 million in support from over 500 backers within just 48 hours. The concept of “washing and reusing filters” instead of replacing them has resonated widely, generating substantial buzz from the outset.
The project page has been flooded with messages expressing anticipation for the washable air purifier, reduced running costs, and its benefits for pet owners.
Expectations from Supporters
Comments on the GREEN FUNDING project page highlight the demand for such an innovation:
-
“I’ve been waiting for a washable air purifier. I’m excited!”
-
“The washable filter is very attractive. I’m supporting it.”
-
“I was always concerned about running costs, so I thought, ‘It’s finally here.'”
-
“I wanted an air purifier with low power consumption and a washable filter.”
-
“It has all the features I want, it’s wonderful!”
-
“I’ve been looking for something like this. I’m eagerly awaiting it!”
-
“I have high hopes for pet hair control.”
-
“I’m looking forward to it because I’m concerned about pet odors!”
-
“I’m happy to be witnessing a moment that will significantly change the history of air purifiers.”
This strong support for the One X stems from its ability to address three key issues.
Eliminating the Burden of Continuous Filter Replacement
Traditional HEPA filters degrade in performance as they clog, leading to annual replacement filter costs that can amount to approximately ¥20,000. The One X’s iCS™ electrostatic dust collection filter requires only water washing when it gets dirty. This restores its performance to like-new condition, effectively making filter costs zero and eliminating disposable waste. This allows for long-term, hygienic use without concerns about replacements.
Tackling Invisible Particles Like Pollen and PM2.5
Many common HEPA filters capture particles down to about 0.3µm. The One X is designed to capture microparticles as small as 0.01µm, approximately 30 times smaller. This capability addresses even the finest pollen and PM2.5 particles that can bypass masks. The applicable area ranges from approximately 10 tatami mats (16㎡) to a maximum of 37 tatami mats (60㎡). With a minimum operating sound of 24dB, it can be used comfortably in bedrooms, even during allergy seasons.
Suppressing “Lingering Odors” from Cooking and Pets
The One X’s Hyper-Ion generator releases 150 million negative ions per cm³, which attach to airborne odor molecules and cause them to settle. Furthermore, in spaces with pets, third-party tests confirm a 98.1% removal of floating pet hair and a 94.7% reduction in ammonia odor. This feature is particularly effective in addressing post-meal cooking odors and characteristic pet smells.
Hands-On Experience Available at Shibuya Exhibition
A limited-time exhibition of the One X is currently underway, offering visitors the opportunity to see, touch, and experience its features firsthand. This allows for a deeper understanding of its appeal beyond specifications and numerical data.
