What is Airsep Focus?

Airsep Focus is a light and portable pulse flow concentrator that gives active individuals the supplemental oxygen they need at low output and capacity. This unit was engineered and designed to provide patients with medical-grade oxygen while still being able to move freely, without feeling held in place by the additional weight.

This unit is perfect for people with limited mobility and those who suffer from chronic shoulder and back pain. It is precisely for patients with mild stage 1 or 2 COPD conditions. 

How Does Airsep Focus Work?

Oxygen concentrators have been around since the mid-1970s. It became the most reliable and convenient source of supplemental oxygen available today. Moreover, they are efficient, cost-effective, and the safest alternative to high-pressure oxygen tanks and cylinders. 

The air humans breathe consists of approximately 78% nitrogen, 21% oxygen, and 1% other gasses. In the Airsep Focus unit, the air in the room passes through a regenerative and absorbent material called a molecular sieve. It is the material primarily responsible for separating oxygen from nitrogen. The result is the flow of high-concentration oxygen delivered to oxygen patients. 

Airsep Focus combines oxygen conserving technology with advanced oxygen concentrator technology to create the world's lightest and smallest portable concentrator unit. This product efficiently produces and releases its oxygen and immediately delivers it as a pulse of oxygen at the beginning of the patient's inhalation. 

Airsep Focus Features

A product's features are what make it stand out from the rest. Unlike other Airsep Focus portable oxygen concentrator reviews, this article will also tackle the unit's features in complete detail!

Design

Being dubbed the lightest portable oxygen concentrator, you can expect the design to be as small as it could get. It is palm-sized, with a compact and sleek design. 

It is smart to carry — one that looks good and can be easily thrown across the shoulders without much worry of ruining your outfit aesthetic since it doesn't look medical at all.

Size and Weight

AirSep Focus is unbelievably tiny compared to other portable concentrators in the market, with dimensions 6.4 high x 4.8 wide x 2.5 deep. That means AirSep Focus is small enough to fit inside a purse or clip in a belt! 

Moreover, this unit weighs only 800 grams, proving that it is the lightest among all POC units. However, note that the battery weighs around 240 grams and must be worn separately. Some people might see this as a hassle, while others like the weight being distributed. 

Regardless, take note of these numbers:

• Unit: 800 g
• Battery: 240 g per battery 2 included
• Optional AirBelt (Battery Belt): 800 grams

Portability

AirSep Focus is leagues ahead of some of its competitors in terms of portability. This model has been found to meet the needs of most individuals with mild respiratory problems. Aside from its petite and portable size, another good feature this unit has that goes well with traveling is the carrying case that comes along with it.

It has an excellent cross-shoulder strap that can help keep the unit close to you. Thanks to the lightweight and small size, you will surely be able to carry this POC around without any trouble or hassle!

LCD screen

The AirSep Focus model does not have an LCD screen. 

Controls

AirSep Focus Portable Oxygen Concentrator is simple to use and operate with its basic controls. There are no settings you will need to adjust. Instead, it is a one-touch operation and merely has an on and off switch and LED lights that indicate the pulse flow and alarm.  

Alarms

This unit has alarms that typically indicate the machine is not working correctly. When the portable oxygen concentrator is operating and does not sense breathing for the past 15 minutes, it will trigger a constant alarm sound, and the amber alarm light will illuminate simultaneously.  

Other triggers for the alarm are low battery warnings, disconnected cannulas, and exceeded capacity.  

Battery

The most important takeaway about AirSep Focus regarding batteries is that it has external batteries only. It has to be worn separately, either on the hip, waist or on the model's shoulder strap. Fortunately, Airsep also offers a bag with battery pockets as part of its accessories for those who do not want to wear the battery belt separately.

Battery Life

Airsep Focus portable oxygen concentrator comes with two external micro-batteries, with a 1.5-hour duration each. To get the whole 3-hour battery life duration, you will need to carry both batteries separately and manually switch the first one with the second as soon as it depletes. 

The battery has a built-in charge indicator that displays how much the battery is charged. The 4 LEDs will flash to show the unit's battery status in 25% increments. The battery will keep charging even when the product runs on AC/DC power. 

You can purchase an AirBelt if you need more battery backup. It can give you an additional 4 hours, which makes a total of 4 hours (3 hours of 2 micro batteries plus the 4 hours of battery belt).

Charging Time

The recharge time of Airsep Focus is 4 hours for the battery pack and 3 hours for the optional AirBelt. 

Power Sources

This unit works on four primary sources:

• Rechargeable battery 2 included
• AC Mains
• DC Power Supply (such as a car charger)
• AirBelt (optional battery belt)

Power Consumption

The Airsep focus unit uses only 65-85 watts of power. If the battery is charging, the energy consumption rises to a modest 75-90 watts. 

Flow Type

Airsep Focus offers a rate of pulse flow settings 2, equivalent to 2 LPM. That is relatively low for many oxygen patients. Though, that is quite expected due to its extremely lightweight and small size. It will come with limitations. 

It better suits patients with only low oxygen needs. Note that the unit only provides pulse dose settings. That means it only releases oxygen when the patient inhales. Therefore, you can't use it alongside PAP devices. 

Sieve Beds

Sieve beds are the filters found inside the concentrator that is in charge of separating the nitrogen from the oxygen in the air. AirSep Focus, to adapt to its small body, uses a smaller compressor, a smaller motor, and of course, smaller sieve beds. The size restriction is also why it only has one oxygen setting, which is the pulse flow setting 2.  

Warm-Up Time

This oxygen concentrator only needs 2 minutes to warm up before you can use it. 

Oxygen Concentration

The unit has an oxygen concentration percentage of 90% oxygen (-3%, +5.5%) in the operating range. 

Capacity

Airsep Focus has one pulse flow setting of 2. Accordingly, AirSep Focus has a low maximum oxygen output of 330 ml/min, which is perfect for those oxygen therapy patients with low oxygen needs. 

Sound Level

The Airsep Focus model produces up to 41 decibels. That is similar to a low and silent hum of a refrigerator, ideal for travel and outdoor use as it won't disturb anyone with its quiet operation. 

Filters

The internal filters are one of the things you need to keep an eye on with your Airsep Focus. They need to be replaced after 5,000 hours of operation. It would be best if you didn't go over that period. 

Since this device supplies you with oxygen, you need to keep the filters clean. Otherwise, you might inhale dust, dirt, and bacteria. That is the last thing you want as an oxygen therapy patient. 

Available Accessories

Airsep Focus has several available accessories:

• Two batteries
• AC/DC Universal Power Supply
• AC/DC Power Cord
• Carry-all Accessory Bag
• Shoulder Strap
• Battery Case
• Battery Charging and Operation Coiled Cords
• Carry Bag with Battery Pockets
• Nasal Cannulas

FAA-Approval

Traveling is one of the many exciting and rewarding things in life. However, being an oxygen patient can put a bit of a damper on those plans. Fortunately, Airsep Focus is one of the POCs that satisfied and met the acceptance criteria of the Federal Aviation Administration. 

Airsep Focus has been approved for onboard medical use. It makes traveling for oxygen patients easy and hassle-free. It has four power source options that guarantee you would not go a minute without pure oxygen.

You can take this unit with you if you travel by plane, car, or ship. It is indeed a great companion for your overseas plans or out-of-town road trip.

Airsep supports customers from around the world with high-quality services and products. Airsep Focus is being distributed worldwide to assist people with oxygen needs. The company has product sales and support in more than 100 countries.

Moreover, it is both FDA and FAA approved.
