I'm using the same filter size the previous resident did, but it looks too small, like air could blow around it? Is this normal? Thanks.

Answer:

Look up actual dimensions of the Honeywell filter number. Its actually 15-7 – 8 that ones only 15.4 buy the right filter and youll be fine. Theyre not cheap though.
