Active Aqua Bug Shield, 8"

Keep Pests and Spores Out of Your Airflow, 8"

An open fan or duct opening doesn't just move air, it's an open door for insects looking for a way in and for the airborne fungal spores that often hitch a ride right alongside them. Active Air's Bug Shield closes that door without closing off airflow: a plastic mesh screen stretches over the opening, held snug by an elasticized rim and cinched tight with an adjustable drawstring, so air keeps moving while pests and spores stay outside.

This 8" Bug Shield is sized for 8" fan and duct openings, matching the larger inline fans and filters used on bigger rooms and multi-light setups.

Key Features & Benefits

• Washable plastic mesh screen — physically blocks insects of all kinds along with the airborne fungal spores that often travel with them.
• Elasticized opening — grips the rim of the fan or duct so the shield stays seated through normal operation.
• Adjustable drawstring — cinches down for a final, custom-tight seal once the shield is in place.
• Washable materials — rinse clean and reuse the shield instead of replacing it every time it picks up dust or debris.
• Suitable for intake or exhaust — works on either side of an airflow setup, wherever pests are most likely to get in.

Who Should Use This Bug Shield

This shield fits growers running fans or ducting who want to block insects and fungal spores at the source, especially in rooms near doors, vents, or outdoor air intakes where contamination risk runs highest. It works equally well on intake air coming into a room or exhaust air leaving it.

Frequently Asked Questions

Does this work on intake and exhaust?

Yes, it's suitable for both intake and exhaust duty, so it can go wherever an airflow setup needs protection. Growers commonly use one on each end of a duct run for full coverage.

How does it stay attached to the fan or duct?

An elasticized opening grips the rim of the fan or duct, and an adjustable drawstring cinches down for a final, custom-tight seal. Together they hold the mesh in place through normal fan vibration and airflow.

Can it be washed and reused?

Yes, it's made from washable materials, so it can be rinsed clean and put right back into service instead of being replaced. That makes it a one-time purchase for most grow rooms rather than a recurring cost.

Does it block fungal spores, or just insects?

Both. The plastic mesh is fine enough to catch insects of all kinds as well as many of the airborne fungal spores that often travel alongside them.

When should I install a bug shield on my airflow setup?

Install one as soon as a fan or duct opening is exposed to open air, particularly near doors, windows, or an outdoor intake where pests and spores are most likely to enter. Retrofitting an existing setup takes only a few minutes since the shield simply stretches over the opening.
