BME280 is by far the best humidity sensor, very fast response. You might not need temperature but the sensor needs it to calculate relative humidity as the dew point changes with temperature. You also get a bonus barometric pressure which can let you know when storms are coming, no difference in air pressure changes in the house so it doesn't matter where you're sensor is. DHT11 suck, don't even go there, very slow resistive sensor that will do neither high or low humidity. DHT22 is ok but struggles on high humidity and takes some time to recover.
