Aller Block Air Conditioner Drain Cap Cockroach Prevention

I am listing these items because I no longer need them due to moving.

1. Allerblock (Ventilation Filter)
This is a ventilation filter that can be cut to size with scissors into a 16cm square.
Please check the photos for applicable sizes.
It is brand new and unused. How about it for those who are about to replace their filter or want to start using one?

2. Insect Repellent Cap - Cockroach Prevention Cap
*The bag has been opened, but the contents are unused.
This is a convenient item that prevents insects from entering by capping the air conditioner's drain hose.
Please refer to the instruction manual in the photos for details.
In my case, the air conditioner's drain hose was already wrapped tightly with tape, so it was already protected. I recommend checking before purchasing.

Please note that these items are sold as a set.
