How to allergy-proof your car

Spring sunshine brings new energy, but for millions of Australians it also marks the arrival of allergy season. Runny noses, itchy eyes and sneezing are common signs of exposure to pollen, dust and other airborne irritants. Many people expect these symptoms in the garden or on a bushwalk. However, fewer know how much exposure happens inside the car.

Pollen from trees and grasses, dust from the road, to the pet hair from your dog’s last adventure. Every time you switch on the air conditioning or open a window, these particles circulate in the cabin. For drivers who suffer from hay fever or asthma, that can mean watery eyes, sneezing and reduced concentration at the wheel.

The good news? A simple car cleaning reset can transform your car into a more comfortable space. With a few simple steps, you can make your car part of your allergy management routine and protect your health and improve road safety at the same time.

Refresh your cabin air filter for allergy relief

Think of your cabin air filter as a shield between you and the outside world. It captures dust, pollen, and even exhaust fumes before they circulate through the car. However, like any filter, it becomes less effective the more it clogs with debris. Most manufacturers recommend replacing it every 12 to 18 months

(or every 15,000 – 30,000 km, whichever comes first), but during high-pollen seasons, a yearly replacement is a wise choice.

If you’re especially sensitive to allergies, consider upgrading to a HEPA (High-Efficiency Particulate Air) filter. These are designed to capture much smaller particles than standard filters, meaning they can trap the fine pollen grains and dust mites that often cause the worst reactions. Ask your mechanic at your next service about suitable filter options for your car model.

Focus on vents and airflow

Dust and mould often collect inside vents, and every time you turn on the fan or air conditioning, they’re blown into the cabin. A good first step is to clean the vent openings. Use a can of compressed air to dislodge hidden debris, then wipe the covers with a damp microfibre cloth and mild disinfectant. If you notice musty smells or visible mould, consider a professional vent clean.

When driving during peak pollen times, usually early morning and evening, keep your windows closed and set your air conditioning to recirculated air mode.

Clean upholstery with care

Seats are another hotspot for allergens, and the material matters:

• Leather or leatherette seats are allergy-friendly because they can be wiped down easily and don’t trap pollen and dander.
• Fabric seats are more common but require extra care. Vacuum them weekly, paying close attention to seams and crevices where particles gather. Once a month, use an upholstery-safe cleaner designed to neutralise allergens.
• If you travel with pets often, consider using washable seat covers. They not only protect your seats but also make cleaning quicker.

Adopt smart habits

Allergy-proofing isn’t just about cleaning; it’s also about prevention. Here are a few easy habits that make a difference and help you focus on the drive:

• Clothes carry pollen: Remove jackets or shake them out before entering the car.
• Pets bring allergens: Brush them before car rides and use washable seat covers.
• Park wisely: Avoid parking under flowering trees where pollen is heaviest.
• Exterior care: Wash your car regularly to prevent pollen on the outside from making its way in.
• On-the-go relief: Keep tissues, eye drops and antihistamines in the glovebox or centre console for flare-ups.

Routine car cleaning checklist for busy drivers

Understandably, not everyone has time for a full detail each week. Here’s a 10-minute routine that helps:

• Shake out and vacuum the floor mats.
• Run a vacuum over the seats.
• Wipe down the dashboard and steering wheel.
• Give the vents a short burst of compressed air.
• Empty rubbish and tissues that may hold allergens.
