8 Air Coolers to Avoid: What Could Hold You Back in 2025

2. Tristar-Power and Coverage Are Limited-($100.6)

The Tristar is budget-friendly and easy to move around, which makes it tempting for quick fixes during heat waves. But don’t expect it to cool large spaces or multiple people effectively. Its airflow is quite low, so you’ll need to sit very close to feel any real difference. If you’re sharing a room or bed, you might actually need two units to get proper coverage, which defeats the purpose of saving money. The lack of advanced controls or a remote might be a plus for some, but it also means less convenience and fewer features overall. If you want a cooler that can handle bigger rooms or provide strong, widespread airflow, look elsewhere.
