I did a ton of research on dehumidifiers after figuring out that my post COVID joint issues were exacerbated by humidity. We live in Florida and relocation isn’t an option right now. I decided to trust the Frigidaire brand an I’m glad I did. According to our Nest thermostat the humidity inside was around 80% prior to use of the dehumidifier, it’s now between 50-60% depending on weather conditions (we’re currently in the rainy season).  That’s enough of a difference for my body to feel normal again so that’s invaluable to me. 
We have an 1800sqft house with an open floor plan. The unit is located close to the center of the main living area and needs emptied 2-3x per day on the dry lo setting. Roughly every 12 hours on auto lo. 

I bought a small off brand dehumidifier for the bedroom first, it helped but it’s only pulling 50oz of moisture per week and is seemingly slowing down after a month.
