We are health advocates and our machines are designed with powerful motors, advanced filtration technology, and ergonomic designs, ensuring both efficiency and comfort, creating a healthier workplace for you and your clients.

What is the difference between Alizé and Maéstro?

The Alizé model is more lightweight and rather flexible on a floor rolling stand and more compact. It has 3 modes of the built-in LED lighting and 3 modes of suction power controlling with the power adapter/controller outside the device that makes it simple to control it on pedicure station.        

The Maéstro model is an upgraded, more powerful version - Ultimate Protection Nail Station. It’s the best option for manicure, pedicure, podology (podiatrics) as it also absorbs smells not only the dust. It has 3 modes of lighting and 3 modes of the light temperature, 3 modes of suction power. It’s more powerful than Alize model (1st mode of Maéstro is the 2nd mode of Alizé). It has the built-in UV disinfection.  The intuitive controlling panel is right on the body of the device and the head rotates 360 degrees.

Are your products noisy?

4BLANC® dust collectors are engineered to deliver strong suction with controlled sound levels for a comfortable working environment.

Average sound levels: 

• Alizé: 74.6 dB 

• Maéstro: 77.3 dB

Actual sound will vary with power mode, distance, and room acoustics. For context, normal conversation is about 60 dB, while a busy street is around 80–85 dB.

What if I need replacement parts?

Replacement parts, such as filters, are available on our website or through official distributors like Amazon. If you lose some parts or want/need a replacement, contact customer support team at info@4blanc.com to order those.

How often should I replace filters? Where to buy and how to install?

Filter life depends on workload and dust volume. For daily professional use, empty and clean the filters once in 2 weeks and replace filters once in 45 days (≈100 procedures for Alizé and 120 procedures for Maéstro). Replace sooner if you notice reduced suction or a visibly saturated filter. Filters and accessories are available on our website; check the installation tips here for Alizé and Maéstro.

Low suction — could it be the filter? How do I clean/check it?

Yes, a saturated or mis-seated filter is the most common cause. Re-seat the filter until you feel/hear a click. 
- Run the napkin test near the intake (levels 1–3).
- Do not wash HEPA filters; replace them. Empty and clean it every 2 weeks, or replace the filter entirely.

I lost the filter cover / need a new adapter — where can I order spare parts?

Spare parts (filter caps, adapters, etc.) are available via our Support team. Share your model and we’ll send options and pricing.

How do I know if a filter is defective/damaged in transit?

If the filter arrives deformed, torn, or the frame is cracked, or you cannot seat it flush and it won’t “click,” contact Support with photos and your order number. We’ll replace defective parts under warranty.

Do the machines come with replacement filters?

They come with a starter filter, and replacements can be purchased through our website or retail partners.
