Is there a different lifespan for the new Dry-Brik II between summer and winter months?
There could be a slight difference, depending on where you live. If you live in a climate where you have a lot of rain, you definitely want to stick to the two-month schedule. If you live in a climate where you have the heat on in your house for several months and it tends to be dry, the Dry-Brik could last a bit longer. Of course if you’re outside shoveling snow and working up a sweat, you’re still accumulating moisture in your hearing instrument, and the Dry-Brik will be “on duty” to adsorb it. Overall, the difference is not significant over the span of a year, so it’s a good idea to get in the habit of changing the Dry-Brik every two months in order to ensure that you have a fresh, charged desiccant at all times. If you change your Dry-Brik II every two months, the average cost will be around $2.00 a month to keep your hearing instruments working at their peak performance.
