Frost King V73/9H Indoor Shrink Window Kit
I use this on exposed pipes in a garage or basement before the first freeze. It slips on easily and cuts with scissors.
Tubular Foam Pipe Insulation
A simple under-door seal that sticks on and blocks cold air without drilling. I would grab it for a front door or a door to a garage.
Holikme Door Draft Stopper 2-Pack, Under Door Seal
An adhesive foam strip for sealing gaps around doors and window sashes. It cuts with scissors and goes on in minutes.
Foam Weatherstrip Seal
A plain pair of blackout curtains that block light and some chill from the glass. They are easy to hang with standard rods.
Amazon Basics Portable Blackout Curtain Shade
A heavy curtain panel I would use on a north-facing window that never warms up. It also muffles outside noise.
NICETOWN White 100% Blackout Curtains 84 inch Long
A warm and cool mist humidifier for a large bedroom or living room. The warm mist helps in the coldest weeks and the remote makes it easy to adjust.
Levoit LV600HH Hybrid Ultrasonic Humidifier
A simple cool moisture humidifier for small to medium rooms. It uses a wicking filter and runs quietly through the night.
