Hi, I’m Mena.
I often hear from people in home caregiving and childcare situations saying, “I’m looking for an electric suction machine, but I don’t know which one to choose.” Because electric suction machines are classified as medical devices, information tends to be scattered, and with price ranges spanning from ¥10,000 to over ¥100,000 — plus the question of whether a device is meant for phlegm suctioning or nasal mucus suctioning — this is a category that’s hard to compare.
In this article, we comprehensively cover the major home electric suction machine models by intended use. From elder care phlegm suction models (Shinei Minick III, Sepa III, PowerSmile series) to infant nasal suction models (Mercyport, SHUPOT), we have organized the actual specs and key selection criteria.
メナChoosing an electric suction machine comes down to your intended use. For phlegm suctioning in home elder care, the Minick III series with suction pressure of -85 kPa and flow rate of 20 L/min or more is the top choice. For infant nasal mucus suctioning, the Mercyport at around ¥10,000 is sufficient. This article will help you find the right model for your needs.
Full List of Recommended Home Electric Suction Machines
Shinei Industry Minick III-S MS3-1000 Electric Suction Machine
メナThe Minick III-S achieves maximum suction pressure of -85 kPa while offering a 2-mode design with a Silent Mode that is easy to use at night. With a 1,000 mL tank and 3.4 kg weight, this standard model handles a wide range of home care needs including phlegm and nasal mucus suctioning.
The Minick III-S (MS3-1000) is the standard model of Shinei Industry’s home electric suction machine series. Despite delivering professional-grade suction pressure up to -85 kPa, it is designed for easy day-and-night use with two-speed switching between Normal Mode (20 L/min) and Silent Mode (13 L/min). The 1,000 mL tank capacity covers the main home care needs of phlegm and nasal mucus suctioning.
It uses a piston-type double-head pump that delivers stable suction power over extended periods. With a continuous use time within 6 hours, it can handle multiple daily suctioning sessions. At approximately 3.4 kg, it is a standard weight for home use and is easy to move on a cart or trolley.
Certified as a controlled medical device (Class 2), it provides guaranteed safety. It has high compatibility with suction catheters and is used widely by both healthcare professionals and home caregivers. As the latest generation of the Minick series, it also improves on older models in terms of control panel visibility and ease of maintenance.
Shinei Industry Minick III-W MW3-1400 Electric Suction Machine
メナThe Minick III-W is characterized by its high-power suction flow rate of 30 L/min (Normal Mode). With a larger 1,400 mL tank, this model is suited for those who need thorough phlegm suctioning covering the entire airway.
The Minick III-W (MW3-1400) is the high-power, large-capacity model for those who need more from the series. The Normal Mode suction flow rate reaches 30 L/min — 1.5 times that of the S model — improving performance when dealing with highly viscous phlegm or suctioning across the full airway. Even in Silent Mode, it maintains 20 L/min, providing ample suction even at reduced noise levels.
The 1,400 mL tank is 40% larger than the S model, allowing continuous operation without frequent tank changes. At approximately 4.6 kg, it is slightly heavier, but this is rarely a concern when used as a stationary unit. For those with tracheotomies or severe respiratory conditions requiring frequent suctioning, the W model’s generous specs provide reassurance.
Like the S model, it uses a piston-type double-head pump for stable long-duration operation. Certified as a Class 2 controlled medical device, it is trusted by physicians and nurses in home medical care. Consumables such as suction catheters and extension tubes are compatible with the S model.
Shinei Industry Sepa III NS3-1400 Suction/Nebulizer Combo
メナThe Sepa III integrates an electric suction machine and a nebulizer (inhaler) in a single unit. It manages both phlegm suctioning and medication inhalation without needing separate devices — the ideal choice for those who feel overwhelmed by the number of home care machines.
The Sepa III (NS3-1400) is a unique model that combines electric suction and inhalation (nebulizer) functions in one unit. The suction circuit and nebulizer circuit are completely separate, allowing both functions to be used hygienically without cross-contamination. It combines maximum suction pressure of -85 kPa with a nebulizer function delivering 0.25 MPa discharge pressure and 10 L/min flow rate.
In home care settings, many people have respiratory conditions such as bronchial asthma or chronic bronchitis, and it is not uncommon to need both phlegm suctioning and medication inhalation. Using the Sepa III eliminates the cost, storage space, and management burden of two separate machines. The tank capacity is 1,400 mL, the same as the W model.
At approximately 4.7 kg, the weight is nearly the same as the W model. The suction function can also be used alone, so it works as a standard suction machine when the nebulizer feature is not needed. Depending on the accessories included, the price ranges from ¥62,700 to ¥86,900, so confirm which accessories you need before purchasing. Certified as a Class 2 controlled medical device.
Shinei Industry PowerSmile Heart KS-800 Electric Suction Machine

The 800 mL tank capacity is easy to manage when washing the tank after each suctioning session.
The AC power input supports 100–240V for international use, making it usable during overseas or extended travel. During power outages, it can switch to DC 12V (cigarette lighter socket) or the built-in battery to continue operating. It features a PTFE filter to prevent liquid from entering the pump — an important safety mechanism for long-term use.
Shinei Industry PowerSmile S KS-710 Electric Suction Machine
メナThe PowerSmile S is an ultra-lightweight model at approximately 1.5 kg, slightly lighter than the KS-800, with AC and DC dual power support. It does not include a built-in rechargeable battery, but its lower price point makes it a popular entry-level choice for cost-conscious buyers.
The PowerSmile S (KS-710) packs maximum suction pressure of -75 kPa and flow rate of 17 L/min into an ultra-lightweight body of approximately 1.5 kg. It supports AC 100V and DC 12V dual power, usable both at home and in a car. It is sold alongside its successor the KS-800 (¥37,500), and those who want to keep costs down often choose the KS-710.
The PTFE filter prevents backflow into the pump, ensuring device durability for long-term use. The 700 mL tank (100 mL less than the KS-800) requires more frequent tank management, but it provides sufficient capacity for daily home care use. Its compact design fits anywhere without storage hassle and sits neatly at the bedside.
It is one of the more affordable options in the Shinei Industry suction machine lineup. It works as a first suction machine for home care or as a backup unit. Consumables like catheters and filters are shared with the KS-800, so if you upgrade to the KS-800 later, you can reuse the same consumables.
Shinei Industry Minick III-SB MS3B Electric Suction Machine with Built-in Battery
メナThe Minick III-SB operates on its built-in battery even during power outages or disasters when AC power is unavailable. With approximately 60 minutes (Normal Mode) and 120 minutes (Silent Mode) of battery operation, it offers great peace of mind for home care households that prioritize emergency preparedness.
The Minick III-SB (MS3B) is the battery-equipped version of the MS3-1000 (Minick III-S). When running on AC power, it delivers the same specs as the S model (max -85 kPa, Normal 20 L/min, Silent 13 L/min), while automatically switching to a built-in Ni-MH battery to continue operation during power outages or disasters.
Battery run time is approximately 60 minutes in Normal Mode and 120 minutes in Silent Mode. For short power outages, it can continue operating until power is restored. In Japan’s disaster-prone environment, for households where residents depend on ventilators or suction machines, power outage readiness is a critical selection criterion for medical safety. It is positioned as the successor to the Minick DC-2.
Priced at ¥96,000–¥116,930 (tax included) — approximately double the S model. If battery function is not necessary, the Minick III-S (¥51,180) offers better cost performance. However, for households with ventilator users or those with severe respiratory conditions, the investment is worthwhile as insurance against power outages. At approximately 3.5 kg, it handles just like the S model.

How to Choose an Electric Suction Machine
Use Case 1: Home Elder Care / Phlegm Suctioning — Prioritize Suction Pressure and Flow Rate
For phlegm suctioning in home elder care, the guideline is suction pressure of -80 kPa or more and flow rate of 17 L/min or more. For highly viscous secretions or full-airway suctioning, -85 kPa and 20 L/min or more (Minick III-S/W) is recommended. Piston-pump models with continuous use time within 6 hours are best suited for extended home use.
Use Case 2: Childcare / Infant Nasal Suctioning — Lightweight, Affordable, Safe
For infant nasal suctioning, -75 to -83 kPa and 12–17 L/min is sufficient. Compact units weighing 0.8–1.5 kg (Mercyport, SHUPOT) are easy to operate one-handed. Prices are also significantly lower at ¥10,000–¥17,000 compared to elder care machines, with a lower barrier to entry.
Use Case 3: Prioritizing Power Outage / Disaster Preparedness — Battery-Equipped Models
For those who must continue using a suction machine during power outages or evacuations, a battery-equipped model (Minick III-SB/WB) is essential. Battery run times of 40–60 minutes (Normal Mode) and 90–120 minutes (Silent Mode) cover short power outages. For extended outages, also consider pairing with a portable power station.

Electric Suction Machine Consumables & Accessories Guide
Regular replacement of consumables is essential for safe, long-term use of an electric suction machine. Here we introduce the main consumables and accessories.
Suction Catheters (Suction Tubes)
A suction catheter is a tube connected to the tip of the suction machine and inserted into the airway or nasal cavity. Clean and disinfect after each use, and replace when deteriorated. The size (Fr/French) varies by product, so choose the size appropriate for the suction machine and user. Compatible catheters are included with Minick III and PowerSmile series units, and they are also sold separately as consumables.
Suction Bottles, Tanks, and Spare Parts
The tank (bottle) that collects suctioned material must be cleaned and disinfected after use. Having a spare tank allows work to continue with a separate tank while another is being cleaned. The Minick III series tanks come in 1,000 mL (SB/S models) and 1,400 mL (W/WB models, Sepa III) capacities. Always use genuine manufacturer parts.
Bacterial Filters / PTFE Filters
The PowerSmile series (KS-710/KS-800) features a PTFE filter that prevents suctioned liquid from flowing back into the pump. The filter is a consumable requiring regular replacement. If you notice a decline in suction power, clogging or deterioration of the filter may be the cause — consider replacing it.
Summary
The best electric suction machine varies greatly depending on “who uses it and for what purpose.” For phlegm suctioning in home elder care, the Shinei Industry (Shinei) Minick III series is the top choice with top-class domestic reliability and a proven track record. If portability and power outage readiness are priorities, consider the PowerSmile series or battery-equipped models.
For infant nasal mucus suctioning only, the C-Star Mercyport and Pigeon SHUPOT offer an excellent balance of price, function, and safety. Compared to manual mouth-suction types, going electric makes a dramatically more effective difference in relieving infant nasal congestion.
メナBefore purchasing an electric suction machine, it is recommended to consult your family physician or visiting nurse. Phlegm suctioning in particular is a medical procedure performed under physician’s instructions. Confirm the appropriate model selection and correct operating method before introducing one.
