A few weeks back I was wondering how the DIY blown in cellulose insulation process was before I did it, but couldn't find any info. So, I am posting this about my experience. I bought 168 packages of the cellulose from Home Depot ($8.96 per bag). We added a 2nd floor addition, so this was for a new construction attic space. The blower was free for 2 days since I bought so many. The blower they gave me was a "Force 1", which they told me was their rental version, not the freebie version. I called the cellulose company before this whole process and they told me I could average 15-17 packages per hour with the standard machine. My wife and I did all 168 packages in about 6.5 hours. It was very easy and faster than I thought. We were blowing the insulation into our attic to a depth of 15". It is very dusty so you do need to where a mask. I was very impressed with the machine. It didn't clog once on us. We were feeding the insulation up 2 floors through 100' of hose. If you can leave the machine outside, I'd recommend it as it puts a lot of dust in the air. We brought it inside as it was cold out.
