Airsep Focus is the smallest Portable Oxygen Concentrator (POC) in market. The product with certain flow limitations is smallest and lightest from all its competitors. The product is designed for active patients who need ‘little’ supplemental Oxygen to carry their routine.
What you would like about Airsep Focus:
- Extremely light – 800 grams
- Palm sized – Smallest POC in market
- Airsep’s Ultra sense technology – High sensitivity – Doesn’t miss to detect a breath
- Easy to use – just an on/off switch
- Smart to carry – Doesn’t look medical
- FAA approved – Can be taken on board; airplane use
- Works well with car charger
- Total battery back-up of 7 hours with AirBelt
- Works well with tubing up to 7.62 meter (25 ft.)
What you won’t:
- Battery not inside the machine. Needs to be carried separately.
- Machine comes with 2 batteries of duration 1.5 hour each. So needs to be manually switched after 1.5 hour for 3 hours duration.
- Flow is limited – provides ‘2 pulse setting’ i.e. equivalent of 2 LPM ‘only’. No reserve if O2 requirement increases in future.
- The machine can’t be set on ‘1 pulse setting’
- No continuous flow option available; can’t be used directly with PAP devices.
Unbelievably small as compared to any other Portable Oxygen Concentrator in market. (6.4” H x 4.8” W x 2.5” D)
The ‘Focus’ unit weighs only 800 grams. The battery weighing about 240 grams has to be worn separately. For some people wearing the battery separately may be a hassle and some may like it because the weight gets distributed.
Unit: 800 grams
Battery: 240 grams per battery (2 included)
Optional AirBelt: 800 grams
The unit is lighter in weight than any of its competitors even if it is worn with both the batteries.
Standard purity like any other concentrator of 90% (-3% / +5.5%) in operating range.
No internal battery; has to be worn separately either on waist, hip or on the unit’s shoulder strap.
Airsep also provides a bag with battery pockets as an accessory for people who don’t want to wear the belt separately. Focus comes with 2 batteries of duration 1.5 hours each and that’s why for getting the complete back up of 3 hours the person has to carry both batteries separately & manually switch to the 2nd battery when the 1st depletes.
The battery has a built in charge indicator which shows how much the battery is charged, the 4 LEDs flash to display the status of battery in 25% increments.
The battery keeps on charging simultaneously even when the unit is running on AC/DC power.
|Battery||1.5 hours||2||3 hours|
|Airbelt||4 hours||1||4 hours|
|2 Batteries + Airbelt||(1.5 + 1.5 + 4) hours||3||7 hours|
AirBelt (Optional Battery belt) can be purchased separately if more battery back-up is required. The AirBelt provides additional 4 hours of battery which makes it total duration of 7 hours (4 hours of belt + 3 hours of 2 batteries).
Recharge time from fully depleted state
- Battery pack: 4 hours
- Optional Airbelt: 3 hours
The Airsep Focus POC works on 4 sources:
- AC Mains
- DC Source (like car charger)
- Rechargeable battery
- AirBelt (Additional Battery belt)
Very small in size; looks good & can be worn on/across the shoulders. The POC is very much wearable.
Provides flow rate of pulse setting of 2 i.e. equivalent of 2 Litres Per Minute only which is quite low for many patients; it would have been great if the machine could provide flow of up to “3 pulse setting” but of course due to its extremely small size and weight this is a limitation.
The machine provides only pulse flow i.e. gives Oxygen only when patient inhales; therefore, can’t be used with PAP devices.
No text display of alarms – therefore, one needs to look at the table of alarms to see which kind of alarm is represented by the visual or audible indicators.
|Low Battery Alarm||Amber Light - 1 - half second flash and a 5 second pause||1- half second beep and a 5 second pause|
|Battery Shut Down||Amber Light - 2 - half second flash and a 5 second pause||2- half second beep and a 5 second pause|
|No Inspiration / Cannula Disconnect (15 minute)||Amber Light - Solid||Continuous Beep|
|Breath Rate Exceeded||Amber Light - 3 - half second flash and a 5 second pause||3- half second beep and a 5 second pause|
|Malfunction||Red Light - 2 - half second flash and a 5 second pause||2- half second beep and a 5 second pause|
- Left - Red LED
- Center - Battery / Charger Cable Connector
- Right - Yellow / Green LED
Warm Up Time
No routine maintenance required. Just an internal filter needs to be replaced after 5000 hours of operation.
The POC has an external power ON/OFF switch used to power on/off the machine from external battery or A/C mains.

Airsep Focus is the right concentrator for those who are looking for a POC that’s not too heavy. We would highly recommend it for people who need ‘little’ supplemental Oxygen & want an independent lifestyle with high mobility. The product is not suitable for people with high/increasing Oxygen demands.
