For Jess Herbert the prevailing smoke around the Port Macquarie-Hastings region can result in so much more than just stinging eyes.

The 18-year-old has Cystic Fibrosis, a condition which impacts her lungs and vital organs. It results in difficulties with breathing.

Jess' condition has been compounded by the Mid North Coast fires, and its resulting smoke around her Port Macquarie home.

The bushfires have resulted in the worse symptoms Jess has ever suffered, without having an infection.

Smoke has left her feeling exhausted due to lack of oxygen and frequent coughing, caused by mucus sitting on her lungs.

Jess' symptoms prompted her to reach out to friend and mentor Rod Marshdale, who lives near Newcastle.

Rod also has Cystic Fibrosis and the pair met through their frequent visits to John Hunter Hospital.

Jess asked Rod if he knew how she could gain access to an air purifier machine.

The machines don't come cheap with some in excess of $1500.

Rod offered to send Jess his, after hearing about her struggles due to the smoke.

Rod wanted Jess to receive it before the forecast catastrophic fire conditions set in on Tuesday, November 12.

At 11am on Monday, November 11 Rod rang a relative and was put in contact with a truck driver from Port Macquarie's Jim Pearson Transport.

Rod met the driver with the air purifying machine and it was transported directly to Port Macquarie.

By 4pm the air purifying machine was in Jess' lounge room and making a world of difference to her health.

The machine has helped Jess sleep during the night and alleviated many of her symptoms to help her breathe.

"I've noticed a 100 per cent difference," she said.

Jess said her condition can be very isolating, due to the amount of time she spends away from family and friends in Newcastle for treatment.

She's missed many occasions including Christmas, birthdays, Mother's Day and family gatherings.

Jess said she is lucky to have such a supportive group of girlfriends and family members.

She is looking forward to a trip with her family to Hamilton Island, thanks to the Make-A-Wish Foundation.

Jess and her mum Rochelle said they are so grateful to Rod and Jim Pearson Transport, for making such a difference to her health.
